NB: I think this is the same root problem as #34, but I'm not sure, so I'm filing this separately.

I do have an Adafruit Feather nRF52840 Express board (this one).
According to the docs (here), it has an UF2-capable bootloader (source).
Before this, I updated the bootloader to the latest version available (0.6.0).

On my Linux workstation (Debian testing, kernel 5.10.0), I tried to upload a new application-firmware to it through cargo-hf2, but the detection logic failed.
The board is properly sitting in bootIoader mode (confirmed by leds status and by the mass-storage device) and waiting for uploads, but it looks like hf2 is not able to enumerate it:

$ lsusb | grep -i nrf52
Bus 001 Device 082: ID 239a:0029 Adafruit Feather nRF52840 Express

$ hf2 --vid 0x239a --pid 0x0029 info
thread 'main' panicked at 'Are you sure device is plugged in and in bootloader mode?: OpenHidDeviceError', ./hf2-cli-0.3.1/src/main.rs:17:14

At the same time, in the same setup I can properly upload my application in UF2 format to the mass storage device that the bootloader provides. These are the details provided by the board bootloader via the mass-storage device:

$ cat ./FTHR840BOOT/INFO_UF2.TXT 
UF2 Bootloader 0.6.0 lib/nrfx (v2.0.0) lib/tinyusb (0.10.1-41-gdf0cda2d) lib/uf2 (remotes/origin/configupdate-9-gadbb8c7)
Model: Adafruit Feather nRF52840 Express
Board-ID: nRF52840-Feather-revD
SoftDevice: S140 version 6.1.1
Date: Jun 19 2021

Looking at the USB descriptors, these are the interfaces I'm seeing:

I'm seeing three interfaces there, but none of them is an HID endpoint. Unfortunately I don't have any other hf2-capable board to compare, but I have a feeling that the problem is there. Do other supported devices directly expose an HID endpoint? How does the CDC endpoint fits in the picture?

It looks like this device supports UF2 uploads through the CDC+serial endpoint (and mass-storage too), but does not directly expose HID. Am I reading this right? If that is the case, is cargo-hf2 supposed to handle this "UF2 without HID" case?

Yeah if they did indeed disabl the hid (hf2) then this tool cant do anything sadly. However you can update the bootloader to a version that has that mode enabled. You might be able to build a new version from source.

Heres the samd bootloader code and the USE_HID define
https://github.com/adafruit/uf2-samdx1/blob/master/src/hid.c#L3

The nrf52 bootloader might be this one?

I just got a Circuit Playground Bluefruit and was hoping that cargo-hf2 would just work, but its obvious why it doesn't. I've went ahead and opened issue adafruit/Adafruit_nRF52_Bootloader#225 to see if any progress can be made upstream.

Just ran into this issue as well, with a different chip (nice!nano) but same bootloader. How would I determine if my bootloader has HID enabled? I am running windows

I have libusb installed for windows, but lsusb does't exist on windows afaik. Here is the hardware info for the device:

This is supposed to show the VID and PID, but its not there...
I do have a raspberry pi I could connect it to, if necessary

Here is the output of lsusb on my raspberry pi:

Yeah your vid pid pair is present in our list

And you're an nrf from adafruit so seems like its probably a related issue.
