enumerate returns a list of devices that I can't find using any other tools.

running

❯ ioreg -p IOUSB -w0                                                                                       ─╯

I'm trying to connect to the nRF52840. It seems that enumerate 's list just doesn't make sense.

Here's the VIDs and PIDs for everything that comes out of enumerate:

It doesn't seem to match the system profiler list:

Any thoughts on how to fix this?

What specifically are you not seeing from hidapi?
DFU is not HID. Many HID devices have multiple usages, which show up as separate "devices" in hidapi.

Oh I see you are looking for HF2 devices, not DFU. From https://github.com/jacobrosenthal/hf2-rs/issues/34 it appears that HF2 isn't correctly identifying as a HID device.

Ah, it seems that HF2 doesn't define interface identification rules and HID isn't picking it up?

https://github.com/microsoft/uf2/issues/25

Is this something that HID should be concerned about, perhaps by adding ad-hoc support, or is the lack of spec around HF2 mean that HID won't support HF2 devices?

I'm a newbie to this - how would I enumerate non-HID devices?

enumerate returns a list of devices that I can't find using any other tools.
running
ioreg -p IOUSB -w0

HID devices not necessary USB devices.

Any thoughts on how to fix this?

There is nothing to fix here. VID/PID does not uniquely identifies a device.
VID + PID + SERIAL_NUMBER + USAGE + USAGE_PAGE does (in most cases).
Not all USB devices are HID devices, and some HID devices are not USB devices.
hidapi enumerates exactly what Operating System threats as a HID device (at least on macOS). Nothing more, nothing less.
