FreeBSD support hidraw in Kernel from 13.0.
By using libusb only, we can only see the HID device from usb. To address this, we implement hidraw backend for FreeBSD.

Just like Linux use libudev to handle usb specified HID stuff (like Manufacture), we use libusb to handle it.

Currently, some stuff like the Report Descriptor parser and error registry routine are copied from Linux and I think they are platform independent. Can we create a common directory or hidraw directory in code then put them inside?

Have tested by the hidtest program.

I'm no expert of FreeBSD, but isn't there a better way to enumerate all devices of a specific class? (like we do it for hidraw on Linux?)
If this is the "FreeBSD-way" - just confirm it

I am not working on USB stuff quiet often. Is there any possibility to have same vendor id and same product id but different manufacturer string?
We cannot use serial number to distinguish them because a half of devices on my environment don't have serial number.
I can use bus and port number to distinguished between them on local machine. But that will needs a for loop each time to enumerate a usb device. I think libudev do the same thing.

libusb_open_device_with_vid_pid does that under the hood anyway.

same vendor id and same product id but different manufacturer string?

Practically unlikely, but very possible - I had identical devices with different FW targeted for different countries, and one of the manufactures was written in CN.
Also, when you have multiple devices, one of the might be already exclusively open by some other application, and libusb_open might simply fail.

That is also the thing I would like to confirm. Each of the usb device have the specified usbhid deivce file. But in other type of the hid device (e.g. iic), it maybe not the case. Do you think fstat to check if file "/dev/hidraw%d" exist a good idea?
Also, I can ask the author of FreeBSD hidraw driver to confirm this.

BTW: when I mentioned linux/hidraw backed - it actually uses libudev for enumeration, and that's not exactly what I meant.
On Linux there is /sys/class/hidraw directory, which contains only hidraw devices, and it is enough to enumerate all /sys/class/hidraw/hidraw* files to get list of all devices.

Otherwise, when devices are getting connected and disconnected, it is possible that /dev/hidraw2 exists, but /dev/hidraw1 - does not, due to being disconnected at some point.

I thinjk that is a good idea, but I don't think it really is nesessary to do so in scope of this PR.
There are really lots of stuff which I'd like to share among beckends, and I think it is going to be some refactoring after all.

I iterate all sysctl "dev.hidraw" subnode like the following code:

The result is as the comment shows.
Then I match all dev.hidraw.%d by sscanf.

Yes, all functionality is fully implemented. I am just thinking if we should use libudev make hidapi more portable.

Fix it:). Forget to fix the warning.

Thanks. The compiler warnings are gone.

The Segfault issue is still there though.

Can you show me where it cause segment fault?
You can use something like lldb with (sudo lldb <binary_location>). Then use r to run.

I found the reason. There are two usb hid driver in FreeBSD. One is uhid, another is usbhid. Only usbhid is compatible with hidraw. Also, unload and try to load usbhid is useless. The effective way to enable usbhid is through

 sudo sysctl hw.usb.usbhid.enable=1

Then when next time it is auto-loaded, the usbhid will replace the uhid:

sudo kldunload uhid.

If uhid is not auto reload:

sudo kldload uhid

Oops. I forget we have udev-devd stuff. Maybe we should use udev also?

I lost context here. What for? Seem like you have all the functionality implemented already. Aren't you?

Yes, all functionality is fully implemented. I am just thinking if we should use libudev make hidapi more portable.

If udev is generally available on FreeBSD and can be used in a similar way as in Linux/hidraw - it is probably a good idea to do so. And probably linux shouldn't be used in that case at all.
But I imagine that is a large change to this PR, so it is up to you.

Thanks. This method works to get hidraw to bound to the device.

Using hidapitester and the FX2HID example to test.

Unfortunately the new hidraw backend does not work. The old libusb backend has the issue mentioned in #274.

Using hidapitester and the FX2HID example to test.
Unfortunately the new hidraw backend does not work. The old libusb backend has the issue mentioned in #274.

I read the issue he describe. So you think it is because usbhid does pass interrupt that report more 64bytes?

No, I am not so sure why this PR (FreeBSD usbhid/hidraw backend) does not work with HID device with reports length greater than 64 bytes.

The original libusb implementation under Linux/FreeBSD will suffer from #274. #728 is supposed to fix that but unfortunately it does not work for me.

Just wondering if which version of FreeBSD you are using to test this PR. Thanks. I will try to test with FreeBSD 14.2 Release as well to see if that makes any difference.

I think it is the problem but I have no way to verify it.

The hidraw works as follow:

  1. hidraw register a interrupt to parent device(hidbus)
  2. hidbus register a interrupt to parent device(usbhid, iichid .. etc)
  3. usbhid register interrupt config to usb_bus
  4. usb_bus read device speed and limit the packet size according to the speed.

I'm thinking maybe resolving symlinks would help inside of hid_open_path, but I don't know if there could be other special files that are hidraw devices but not located at /dev/hidrawX but otherwise a valid hidraw devices...

(at least on Linux I believe something like that possible with udev rules)

Fix first problem.

For second problem, please see the comment at hid_create_device_info_by_hidraw_idx.
This function return the last element. Before return, it set the next element of the last element as the first element.
So using devinfo->next actually get the first element. Also, we have to set the devinfo->next = NULL as it point to the first element. That is the reason why we have infinity loop previously.

@wulf7 are you sure?
I believe this entire implementation should be about hidraw, not uhid, and according to https://man.freebsd.org/cgi/man.cgi?hidraw(4)

In the hidraw mode, the first byte should be set to 0 and the report data itself should begin at the second byte.

I.e. - no strip.

Sorry about the confusing code. I would like to clarify first that I think using hidraw mode is better for supporting non-usb hid device (e.g. iichid). I clean up the code so that there is hidraw mode only.

If they are compatible, then what point of using both?

HIDAPI is intended to be as thin wrapper as possible for HID device drivers (libusb backend is a different story, of course), with uniform API across platforms.
The way I see it - hidraw mode has simpler and more alike API for HIDAPI to be used as is, when uhid requires additional tracking of current operational mode and handling report IDs in some cases.

Do I miss something about uhid worth mentioning in this scope?

They are comparable but not compatible.

uhid API may be used with old uhid(4) driver.
hidraw API is simpler for implementation and may reuse existing Linux support code.

FreeBSD hidraw(4) supports both. Choose one you prefer but do not mix them.

Now after switching to hidraw mode, it is better to replace all remaining HIDRAW_* ioctls with HIDIOC* ones.
The only exception may be HIDRAW_GET_DEVICEINFO as it provides device serial number which is unavailable through hidraw API

Ooops. FreeBSD hidraw API is outdated. It misses HIDIOCSOUTPUT and HIDIOCGINPUT ioctls.
Although it is easy to implement them, they won`t hit the tree until FreeBSD 14.3 or even 14.4.
So, the uhid API is the only option for 14.2 and earlier.

Can I do it seperately? I think it needs some version check code to enable it.

BTW, thought I don't buy the chip you have, I found 1 stm32f103 in my bedroom yesterday. Then I try to reproduce your environment.

I have the following questions:

Is the wMaxPacket under 64bytes with multiple transport of blocks or wMaxPacket > 64?

Is your condition as following?

  1. Had a device's descriptor larger than 64 byte on full speed device.
  2. Try to send the report
  3. hidapi_read return immediately and the length is 0.

If so, I can reproduce it throught stm32f103 as I set the Input Descriptor to 1023 bytes.

Or

  1. Had a device's descriptor larger than 64 byte on full speed device.
  2. Try to send the report
  3. hidapi_read blocking and never return, returned by timeout.

No matter the wMaxPacket number, but rather the HID report length (Input report or Output report in my test, not so sure about Feature report).

BTW, my device is a high speed USB device (Cypress EZ-USB FX2LP). But it does not matter.

Is your condition as following?

  1. Had a device's descriptor larger than 64 byte on full speed device.
  2. Try to send the report
  3. hidapi_read return immediately and the length is 0.

If so, I can reproduce it throught stm32f103 as I set the Input Descriptor to 1023 bytes.

Or

  1. Had a device's descriptor larger than 64 byte on full speed device.
  2. Try to send the report
  3. hidapi_read blocking and never return, returned by timeout.

HID report length greater than 64 bytes will cause issus to this PR. The current libusb backend also got the issue.

I am using hidapitester to carry out the test so it is not that easy to differentiate the two cases you mentioned.

In any case, it is good that you can at least reproduce the issue (first case). You can also try to change 1023 to something like 80, 128 or 512 to see if the issue still exist.

Then you can try to debug the issue to see if it is related to FreeBSD hidraw implementation or your PR.

The IOCTLs have been added to FreeBSD on 27-April-2025.

 #define	HIDIOCSINPUT(len)	_IOC(IOC_IN,    'U', 38, len)
 #define	HIDIOCGINPUT(len)	_IOC(IOC_INOUT, 'U', 39, len)
 #define	HIDIOCSOUTPUT(len)	_IOC(IOC_IN,    'U', 40, len)
 #define	HIDIOCGOUTPUT(len)	_IOC(IOC_INOUT, 'U', 41, len)

Can I do it seperately? I think it needs some version check code to enable it.

Yes. That can be another follow-up PR.

BTW, thought I don't buy the chip you have, I found 1 stm32f103 in my bedroom yesterday.

Yes, STM32 MCU is a good one to use.

Then I try to reproduce your environment.
I have the following questions:
Is the wMaxPacket under 64bytes with multiple transport of blocks or wMaxPacket > 64?

No matter the wMaxPacket number, but rather the HID report length (Input report or Output report in my test, not so sure about Feature report).

Oops, I thought you are using FULL speed device (64byte packets) with hid descriptor larger than 64byte. That is why I ask you what is the value of wMaxPakcet. Because I though you are using an device unable to configure from stm32cubemx(If you type you want to configure packet size higher than 64, you needs to be the HIGH speed device)

So you are using the HIGH speed? If so, I needs extra hardware to test it. HIGH speed needs MCU have clock higher than 120Mhz. It is impossible for stm32f103. I am trying to find an available stm32f405 to test it.

In the current modification, I support HIDIOC family ioctl for all and use ifdef to provide backward support, you can test it with the new 14-STABLE or 15-CURRENT but I thought they will have the same result.

Besides, I make hidtest compiles hidtest_hidraw and hidtest_libusb.

Now I am clean of the fault, it is the same as what you see. No timeout, immediately exit.

hidapi_read return immediately and the length is 0

Are you saying that you no longer have issuses with your own full speed STM32 MCU implementation if the HID Input/Output report length are larger than 64 Bytes? Or you still have the issue?

If possible, please post the USB descriptors of your device and the test results. Thanks.

Now this PR is much better -- at least it works for USB Full Speed device under FreeBSD 15 Current. I will test under FreeBSD 14.2 Release later.

Ok, I see. I should take some time to get a device able to afford USB HIGH speed

Are you saying that you no longer have issuses with your own full speed STM32 MCU implementation if the HID Input/Output report length are larger than 64 Bytes? Or you still have the issue?

If possible, please post the USB descriptors of your device and the test results. Thanks.

Yes, hid full speed with larger than 64 byte report works.

@aokblast

If you can, please get the FX2LP break-out board from Taobao/AliExpress/Amazon/etc. It is pretty cheap.
FX2LP

FW binary and source codes are here.

It is a quick minor modification of Jan Axelson's FX2HID example from here.
http://janaxelson.com/hidpage.htm
http://janaxelson.com/files/fx2hid.zip

There may be a bit of challenge if you want to rebuild the source code as it may require a full version of Keil C51 compiler. I happen to have access to a pretty old version of Keil C51 compiler at work. I am not so sure about the efforts to port the code to use the free sdcc toolchain. It may be possible because of the nice sdcc based libraries.

  1. https://github.com/djmuhlestein/fx2lib
  2. https://github.com/whitequark/libfx2

Jan's HID page has some other FW as well, for example, for Microchip USB PIC18. I was able to use that as a base for my other HIDAPI testing but I have not figured out how to increase the HID report size above 64 bytes with that FW. I have the PIC18F87J50 USB PIM (free tool from Microchip many years ago).

Since you two are the FreeBSD power user I know of, please help to check if you can give this PR a try. You need to use FreeBSD 14 Stable or 15 Current. Thanks.

This has something to do with avrdude as well. For example, if it works, it is a potential workaround for Issue #274.

FreeBSD HIDAPI is now based on libusb, so it is affected by the Issue #274.

Great.

Test steps: make sure you use the hidraw driver.

  1. Test with your normal generic USB HID device using hidapi's built-in hidtest and hidapitester. This should be okay.
    https://github.com/todbot/hidapitester

  2. Test with USB Full Speed HID device with >64 Bytes HID report size. This should be okay.

  3. Test with USB High Speed HID device with >64 Bytes HID report side. This somehow failed for my test device.

I have mentioned my test device in the comments above.

@aokblast
That will be great. It will be good to test this PR with different test devices.

I tend to believe my modification FW may not be totally correct (interrupt transfer for the IN/OUT endpoint may be correct; Control Transfer to the IN/OUT endpoint may need to be checked). I am not a progammer myself and my main contributions for the Open Source projects (eg: libusb, libusb-win32, libusbK, avrdude, pyusb, libusbdotnet, libftdi and OpenOCD) are mainly on the testing and technical side.

STM32 is a popular ARM Cortex MCU family and STM32H750 is a powerful one, very good for libusb and hidapi related testing.

If you need Super Speed USB testing device (probably not needed for hidapi but more for libusb project), I will highly recomemend EZ-USB FX3 board, CYUSB3KIT-003 EZ-USB™ FX3 SuperSpeed explorer kit, at US$$45.93 plus shipment.

Pull request overview

This PR adds a new FreeBSD HIDRAW backend to HIDAPI so FreeBSD (13.0+) can enumerate and access HID devices via /dev/hidraw*, while still leveraging libusb for USB-specific metadata (e.g., manufacturer string).

Changes:

  • Introduce a new freebsd/ backend implementation (hid.c) and integrate it into both CMake and Autotools builds.
  • Update build/test targets to build both hidraw and libusb variants on FreeBSD (hidtest + testgui).
  • Adjust FreeBSD libusb build artifacts naming to match the -libusb convention.

Reviewed changes

Copilot reviewed 14 out of 14 changed files in this pull request and generated 18 comments.

  • Autotools config only generates pc/hidapi-hidraw.pc and pc/hidapi-libusb.pc when os == linux, but the top-level Makefile.am now installs those pc files for FreeBSD as well. This will break make/make install on FreeBSD because the .pc files won't be configured/generated. Update this conditional to include FreeBSD (or generate the correct pc files based on OS_FREEBSD).

## Pull request overview This PR adds a new FreeBSD HIDRAW backend to HIDAPI so FreeBSD (13.0+) can enumerate and access HID devices via `/dev/hidraw*`, while still leveraging libusb for USB-specific metadata (e.g., manufacturer string). **Changes:** - Introduce a new `freebsd/` backend implementation (`hid.c`) and integrate it into both CMake and Autotools builds. - Update build/test targets to build both `hidraw` and `libusb` variants on FreeBSD (hidtest + testgui). - Adjust FreeBSD libusb build artifacts naming to match the `-libusb` convention. ### Reviewed changes Copilot reviewed 14 out of 14 changed files in this pull request and generated 18 comments. <details> <summary>Show a summary per file</summary> | File | Description | | ---- | ----------- | | testgui/Makefile.am | Build FreeBSD testgui against both `freebsd` hidraw and `libusb` backends. | | src/CMakeLists.txt | Add FreeBSD platform branch to build/export the hidraw backend from `freebsd/`. | | libusb/Makefile.freebsd | Rename manual FreeBSD libusb targets to `*-libusb` naming. | | libusb/Makefile.am | Rename FreeBSD libusb Automake library target to `libhidapi-libusb.la`. | | hidtest/Makefile.am | Build both `hidtest-hidraw` and `hidtest-libusb` on FreeBSD. | | hidtest/CMakeLists.txt | Enable building `hidtest_hidraw` on FreeBSD when `hidapi::hidraw` exists. | | freebsd/hid.c | New FreeBSD hidraw backend implementation (enumeration, IO, descriptors, strings). | | freebsd/Makefile.am | Automake build for `freebsd` hidraw library. | | freebsd/Makefile-manual | Manual makefile to build the FreeBSD hidraw backend. | | freebsd/CMakeLists.txt | CMake target for FreeBSD hidraw backend and pkg-config generation. | | freebsd/.gitignore | Ignore build artifacts under `freebsd/`. | | configure.ac | Switch FreeBSD Autotools backend to `freebsd` and add FreeBSD Makefile/config vars. | | Makefile.am | Add `freebsd/` subdir and install FreeBSD pkg-config files for hidraw+libusb. | | CMakeLists.txt | Add FreeBSD options for building hidraw and libusb implementations. | </details> <details> <summary>Comments suppressed due to low confidence (1)</summary> **configure.ac:249** * Autotools config only generates `pc/hidapi-hidraw.pc` and `pc/hidapi-libusb.pc` when `os == linux`, but the top-level `Makefile.am` now installs those pc files for FreeBSD as well.

libusb_get_string_descriptor_ascii() returns a negative libusb error code on failure, not 0. The current len == 0 check will miss errors.

hid_get_report_descriptor() returns buf_size (a size_t) from a function returning int. This can trigger warnings and truncation on large descriptors. Follow the pattern used by other backends: clamp to INT_MAX if needed and return (int)buf_size after copying.

hid_create_device_info_by_hidraw_idx() always frees template at end: but returns cur. If get_next_hid_usage() never yields a usage (loop not entered), cur is still template, so this returns a pointer to freed memory. Rework the list construction/cleanup so the returned node is never freed (and consider avoiding the circular-list hack).

The VID/PID filter is incorrect: (vendor_id != tmp->vendor_id && product_id != tmp->product_id) will keep devices when either VID or PID matches. It should filter each field independently (like the Linux backend). Also, when the device is filtered out, tmp (and its linked list) is leaked because the code continues without freeing it.

Just wondering if it is worth asking Github Copilot to review this PR.

Although some reluctance it seems to provide reasonable and constructive review at least there will be some hints :-)

Summary of the above test for the EZ-USB FX2LP modified Generic HID example with 128 Bytes report size (high speed USB device).

  1. libusb backend from git (same for PR #730) will only be able to get 64 bytes Input Report. This is a known issue.
  1. PR #728 fixed the above issue and it is able to read back 128 bytes Input Report
  1. Somehow FreeBSD hidraw backend does not work in this case.

usbhid allocates internal buffers based on report size. They are 128 bytes long in that case. 129 bytes wont fit them.

There is a difference between input and output unnumbered reports.
In Linux and hidraw after than leading byte of output unnumbered report is stripped so it becomes a 128 byte. But input reports still go AS IS.

This is under Linux.

Linux hidraw backend does not work if I send 64 bytes payload.
Linux libusb backend does work if I send 64 bytes payload.

Linux libusb backend does work if I send 64 bytes payload. ``` mcuee  ~/build/cypress  16:48  cyusb_linux QSocketNotifier: Can only be used with threads started with QThread (cyusb_linux:26002): Gdk-CRITICAL **: 16:48:33.678: gdk_wayland_window_set_dbus_properties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed Found Hex format file Releasing FX2 CPU from reset mcuee  …/hidapitester   main ?   v15.2.0  16:54  sudo ./hidapitester_git_hidraw --vidpid 0925:1234 --open --buflen 256 -l 129 --send-output 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128 --read-input Opening device, vid/pid: 0x0925/0x1234 Writing output report of 129-bytes...wrote 129 bytes: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F 80 Reading up to 129-byte input report, 250 msec timeout...read 128 bytes: 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F 80 00 Closing device mcuee  …/hidapitester   main ?   v15.2.0  16:54  sudo ./hidapitester_git_hidraw --vidpid 0925:1234 --open --buflen 256 -l 65 --send-output 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64 --read-input Opening device, vid/pid: 0x0925/0x1234 Writing output report of 65-bytes...wrote 65 bytes: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 Reading up to 65-byte input report, 250 msec timeout...read 0 bytes: Closing device mcuee  …/hidapitester   main ?   v15.2.0  16:54  sudo ./hidapitester_git_libusb --vidpid 0925:1234 --open --buflen 256 -l 65 --send-output 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64 --read-input Opening device, vid/pid: 0x0925/0x1234 Writing output report of 65-bytes...wrote 65 bytes: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 Reading up to 65-byte input report, 250 msec timeout...read 64 bytes: 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 00 Closing device ```

That should be the correct one.

The report ID 00 for the output report is not really on the wire. It is more needed because of Windows native HID API.
The report ID 00 is also not on the wire.

Strange. I have just tested FreeBSD hidraw on MBP8,1 with USB touchpad. Touching of surface with all 10 fingers gave me 338bytes packets successfully received.

Good one. Do you have any High Speed USB HID device?

As I mentioned before, "forcing the device to run in Full Speed mode and now this PR works". So your device is most likely a Full Speed USB device.

Latest version of VirtualBox does not seem to allow me to disable EHCI support so I can not carry out the test. I am not so sure if I still have working USB 1.1 Hub to try.

On the other hand, High Speed USB HID device is probably rare. In that case, we may still want to merge this PR first and then debug the issue later.

Maybe it has nothing to do with this PR but rather the hidraw (usbhid driver) of FreeBSD.

The following command seems to disable EHCI driver completely, but then somehow I cannot attach the FX2LP USB HID device. Only a generic Atmel STK600 can be attached.

The following command seems to disable EHCI driver completely, but then somehow I cannot attach the FX2LP USB HID device.

Okay, this seems to work.

PS C:\Program Files\Oracle\VirtualBox> .\VBoxManage modifyvm "freebsd" --usb-ohci on --usb-ehci off --usb-xhci off

Now it seems to work.

Going back to the device with HID Input/Output report size of 128 bytes.

It seems to this PR will work fine as well.

Good thing -- PR #728 also works fine.

So basically this PR works with Full Speed USB HID device, but somehow it does not work with High Speed USB HID device. It may not be an issue with this PR, but rather the hidraw driver issue under FreeBSD.

@Youw

I am still in favour of merging this PR after your review. The reason is that High Speed USB HID devices are not that common. But you can decide.

It is definitely FreeBSD usbhid issue or may be bad interaction between FreeBSD and VBox.

Ouch. It seems that input is really 128 bytes no 129.

That should be the correct one.

The report ID 00 for the output report is not really on the wire. It is more needed because of Windows native HID API. The report ID 00 is also not on the wire.

Ah yes. Sorry for missing this.

Test log.

Edit: this test is not using the latest push today but previous version. I will test that later.

Interestingly it works every other time. Looks like there may be a data toggle related issues.

Supposedly EZ-USB FX2LP can handle data toggle bit automatically.

The above is not the issue of this PR though. libusb backend has the same issue. So does PR #728.

Unfortunately this PR does not work.

PR #728 also does not seems to work either. Strange.

This looks like a firmware bug, right?

Not really in this particular case.

More like a FreeBSD USB bug to me since other Operating Systems have no issues.

Also EZ-USB FX2LP is supposed to handle data toggle correctly from HW side.

BTW, this original FW comes from Jan Axelson, no modification from my side.

If possible, please get the cheap EZ-FX2LP board from online store and try yourself.

For anyone interested in High Speed USB development and testing, EZ-USB FX2LP is highly recommended. The board is pretty cheap to get from 3rd party vendors (cheap clone of CY3689 EZ-USB FX2LP Discovery Kit)
https://www.infineon.com/assets/row/public/documents/24/44/infineon-cy3689-ez-usb-fx2lp-discovery-kit-quick-start-guide-usermanual-en.pdf

For anyone interested in Super Speed USB development and testing, EZ-USB FX3 is highly recommended. The board is not that cheap but still manageable. It used to be at around US$50 but now it is at US$90.15.

I am stilll using VirtualBox VM under Windows 11 for this test, but I have switched the VM back to the default USB configuration (OHCI + EHCI).

PS C:\Program Files\Oracle\VirtualBox> .\VBoxManage modifyvm "freebsd" --usb-ohci on --usb-ehci on --usb-xhci off

Then I use my trusted modified Generic PIC USB HID example (modified from the Lakeview Research Generic HID example to add Input/Output/Feature report IDs). It is a Full Speed USB device.

It was mentioned in the following discussion.
https://github.com/libusb/hidapi/discussions/590

FW source code and old libusb test codes are here.
https://github.com/mcuee/picusb/tree/master/lvr_genhid_mod

The device works well under Windows.

It also works fine with this PR under FreeBSD VM.

EZ-USB FX2LP

Just buy a EZ-USB FX2LP. I spend two days on configuring stm32h750 + usb3320 and it fails. I think there are some design flaws on stm32h750 as some pin output doesn't follow the ulpi standard.

See: https://community.st.com/t5/stm32-mcus-embedded-software/stm32h750-usb3300-no-signals-on-ulpi/td-p/225293?fbclid=IwY2xjawRdSk5leHRuA2FlbQIxMABicmlkETF1eVg0M2d2OENpV1lWdnpjc3J0YwZhcHBfaWQQMjIyMDM5MTc4ODIwMDg5MgABHr4fjotlcri4aRfLeR3qxxa3_rOWLG8XdiaZHQXLlSejiReV3U-u7F052oj-_aem_DLqIO7VIk_LDjl6YhWkqEw

Hi,

I received the EXUSB FX2 last week. I spent the weekend setting up the toolchain, since the SDK is very outdated and Infineon no longer maintains or provides the download link. I’ve fixed the firmware now.

The issue turned out to be quite simple: you forgot to arm EP1OUT the first time. To fix it, add:

EP1OUTBC = anynumber;

at the end of TD_Init().

FX2 last week. I spent the weekend setting up the toolchain, since the SDK is very outdated and Infineon no longer maintains or provides the download link. I’ve fixed the firmware now. The issue turned out to be quite simple: you forgot to arm EP1OUT the first time. To fix it, add: EP1OUTBC = anynumber; at the end of TD_Init(). ``` sudo ./hidapitester --open-path /dev/hidraw4 --buflen 256 -l 129 --send-output 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128 --read-input Opening device. path: /dev/hidraw4 Writing output report of 129-bytes...wrote 129 bytes: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F 80 Reading up to 129-byte input report, 250 msec timeout...read 128 bytes: 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F 80 00 ```

@mcuee I also did some experiments. FX2 is packet-based, which means if you set MPS = 64 and the report size = 128, it will not work correctly when the device wants to send a short packet (< 64 bytes). The reason is the following:

xHCI assumes there will be 2 packets (128 / 64), so it sends the following sequence to the device:

IN token with size = 64
Device replies with 64 bytes
Host ACK
Another IN token with size = 64
Device replies with another 64 bytes
Host ACK

This completes a full cycle for receiving a 128-byte report from the device.

However, if the device sends a short packet, the sequence becomes:

IN token with size = 64
Device replies with a short packet (== 64 bytes)
Host ACK
Another IN token with size = 64
Device never replies, so xHCI never completes the transfer

As a result, the receive operation eventually hangs and fails.

Thanks a lot for the updates. Let me digest and check again.

You are absolute right here. I have seen strange issues previously with random data for the initial run. I am not the author of the origina FX2HID code. The original auther is Jan Axelson (author of the book "USB Complete").

I also did some experiments. FX2 is packet-based, which means if you set MPS = 64 and the report size = 128, it will not work correctly when the device wants to send a short packet (< 64 bytes).

I am not so sure about this one. Different OS may be different as well. Let me check.

@aokblast

BTW, EZ-USB FX2LP is a High Speed USB device, do you mean to say EHCI and not xHCI?

I also did some experiments. FX2 is packet-based, which means if you set MPS = 64 and the report size = 128, it will not work correctly when the device wants to send a short packet (< 64 bytes).

Another thing, I have tested different firmwares. So you may get confused here.

  1. Some of the firwares only have 2 bytes HID reports, like the original FX2HID example (High Speed USB, which also works under Full Speed USB).
  2. Some of the firmwars only have 3 bytes HID reports, like the following USB PIC example (Full Speed USB). I have not tested the later mod with 32Bytes/64Bytes reports.
    https://github.com/mcuee/picusb/tree/master/lvr_genhid_mod
  3. Then I have the modified FX2HID with 64Bytes/128Bytes/512Bytes/1024Bytes firmware. But the 512B/1024B firmware are not well tested across different OS. There may be more bugs inside.

I will carry out tests under FreeBSD over the weekend.

@aokblast

BTW, EZ-USB FX2LP is a High Speed USB device, do you mean to say EHCI and not xHCI?

USB standard is a little bit confusing. You actually attached a USB 2.0 device to xHCI. But since the xHCI controller is a xHCI controller + eHCI controller internally, so...

I also did some experiments. FX2 is packet-based, which means if you set MPS = 64 and the report size = 128, it will not work correctly when the device wants to send a short packet (< 64 bytes).

I found a bug in the FreeBSD xHCI implementation that cause the data only receive bi-transfer in <= 64 byte case. Please also apply this patch while you are testing. https://reviews.freebsd.org/D57146.
I have tried send 64 bytes (report size is 64), send 63 bytes (report size is 64), send 128 bytes (report size is 128), send 63 bytes (report size is 128).

Send 64 bytes (report size is 128) can not be resolved as the problem I have explain previously. There is a flag in libusb call LIBUSB_TRANSFER_ADD_ZERO_PACKET that can solve this problem.

@mcuee 3 bytes also work in both 64 and 128 bytes report. 2 bytes won't work as it is a hard limit in FreeBSD hidraw interface. If you need a ISO image to test, I can build one for you with my patch.

Thanks a lot for the updates. Let me digest and check again.

The issue turned out to be quite simple: you forgot to arm EP1OUT the first time

You are absolute right here. I have seen strange issues previously with random data for the initial run. I am not the author of the origina FX2HID code. The original auther is Jan Axelson (author of the book "USB Complete").

@mcuee 3 bytes also work in both 64 and 128 bytes report. 2 bytes won't work as it is a hard limit in FreeBSD hidraw interface. If you need a ISO image to test, I can build one for you with my patch.

Indeed 2 bytes will not work with FreeBSD hidraw backend. libusb backend works fine (git or PR #728)

I will carry out more testing later today and tomorrow.

Thanks a lot for the updates. Let me digest and check again.

The issue turned out to be quite simple: you forgot to arm EP1OUT the first time

You are absolute right here. I have seen strange issues previously with random data for the initial run. I am not the author of the origina FX2HID code. The original auther is Jan Axelson (author of the book "USB Complete").

I have approved this PR.

@Youw
Please review and I think this is a good addition to hidapi under FreeBSD. Since this is a new backend, it does not affect much other codes. Issues specific to this backend can be fixed within this backend.

BTW, somehow your ISO image only works under VirtualBox VMs, I could not install it under an Intel N100 mini PC, not so sure about the reason (kernel panic). Therefore I cannot test it under physical machine as of now.

Just FYI only.

Now I am lazy to build FreeBSD using source code. I only did that a few times when HPS was developing the new FreeBSD USB Stack many years ago.

Hi, is there any crash log?

Hi, is there any crash log?

Let me capture the crash log over the weekend. I will also compare with FreeBSD 16.0-Current Snapshot.
https://download.freebsd.org/ftp/snapshots/amd64/amd64/ISO-IMAGES/16.0/

I have a few Chuwi Herobox mini PCs running Linux and BSDs. All of them have 8GB RAM. Each has the original 256GB SSD and one more SATA SSD (128GB or 256GB).

Intel N4500 Mini PC -- OpenBSD 7.8 (will upgrade to 7.9 later) and NetBSD 10.1
Intel J4125 Mini PC -- Debian 13 and FreeBSD 15 Release
Intel N100 Mini PC -- Ubuntu 26.04 + Fedora 44 on the main SSD, CachyOS on the secondary SSD
Intel N100 Mini PC -- Ubuntu 26.04 + Fedora 44 Silverblue on the main SSD, EndeavourOS on the secondary SSD.

I will kill the two Arch Based Linux distros (not really using them much) and install FreeBSD/OpenBSD.

For quick testing I recommend VENTOY [1] it provides USB BOOT menu supporting MBR/GPT/BIOS/UEFI where you can choose ISO from the same pendrive to boot. So you can have multiple images on the same bootable pendrive.. and you can use it for storage as well :-)

Please let me know if there is anything to test on FreeBSD 14 :-) I can also boot of 15 or 16 if needed :-)

Hi, is there any crash log?

Sorry I made a mistake, it is not kernel panic, rather the system does not recognize the USB Flash Disk as bootable at all.

I tried the latest snapshot (FreeBSD-16.0-CURRENT-amd64-20260525-490c53e9353f-286096-disc1.iso) and the issue is the same, tested with two USB Flash disks.

Then I tested OpenBSD 7.9 release and it is able to boot (but then it does not recognize the wired and wireless network adapter).

There is a known hardware bug in Alder Lake processors. See https://lists.freebsd.org/archives/freebsd-current/2025-January/006984.html

Interesting.

Is it possible to choose EFI file from your UEFI?

Using Ventoy and then I can do that.

Interesting findings -- now FreeBSD 15.0 Release and OpenBSD 7.9 can boot and I have installed them to the second SATA SSDs of the two Intel N100 Mini PCs. Somehow I need to use HTTP install.

For the FreeBSD 16.0-Current images (your version or the snapshot version), both will fail to boot.

All in all, looks like the issue is related to file system corruption.

Codex updated the PR branch and pushed a186873:

  • Merged current master (518fbd1) and resolved the Autotools/build-system conflicts.
  • Fixed the FreeBSD hidraw backend findings around enumeration/list ownership, allocation and handle cleanup, bus/device metadata, report-ID/report-descriptor handling, error propagation, read-only enumeration, and C++ compatibility.
  • Integrated and exercised both FreeBSD backends through Autotools, CMake, Meson, manual builds, and pkg-config; added a warnings-as-errors C++ build for the new backend.
  • Added runtime pkg-config consumers plus installed shared/static CMake export consumer tests for both hidapi::hidraw and hidapi::libusb, following the pattern from #831.
  • Ran a fresh read-only Fable 5 review and addressed the new actionable findings.

Validation completed locally across Autotools, CMake shared/static, Meson, pkg-config, and installed export consumers. All PR checks are now green, including the native FreeBSD job and AppVeyor.

Related to #274. Fixes #543.
