Unable to use FIDO security key

[cwt]

I use Feitian (Yokey), and Chris also uses YubiKey at 16:55 in this video: https://youtu.be/Na6PT4npsMg?si=ChTsqhIDu-eMq737&t=1015. Both brands were not working because the options CONFIG_USB_HIDDEV and CONFIG_HIDRAW were not enabled in the kernel.

I recompiled my kernel with both options enabled, and my FIDO key works again.

Came here to report the same and to request similarly.

For example in https://wiki.gentoo.org/wiki/PAM/U2F they describe it well

Kernel

Most U2F USB keys identify themselves as raw HIDs (Human Interface Devices). Two kernel configuration modules are needed:

CONFIG_HID
CONFIG_USB_HIDDEV

Enable support for USB Human Interface Devices

Device Drivers --->
   [*] HID Devices --->
     [*] /dev/hidraw raw HID device support
     ...
     USB HID support --->
       [*] /dev/hiddev raw HID device support

In many situations, this kernel configuration is already active. If support for /proc/config.gz is enabled, then the following command can verify proper support is available in the running kernel: zgrep -E "HID(DEV|RAW)" /proc/config.gz

Running that kernel config support check command on my StarFive VisionFive 2 shows that in the kernel included with the Debian image that is distributed via https://rvspace.org/en/home these options are currently not enabled:

zgrep -E "HID(DEV|RAW)" /proc/config.gz

# CONFIG_HIDRAW is not set
# CONFIG_USB_HIDDEV is not set

cat /proc/version

Linux version 6.1.31-starfive (leo@leo-virtual-machine) (riscv64-unknown-linux-gnu-gcc (g2ee5e430018) 12.2.0, GNU ld (GNU Binutils) 2.40.0.20230214) #1 SMP Mon Mar  4 21:31:49 CST 2024

Please turn these on in the kernel build config.

I am using a Ledger Nano X hardware device with Fido U2F on it, connected to my VisionFive 2 by USB, and already added the udev rules from https://github.com/Yubico/libfido2/blob/main/udev/70-u2f.rules but that is not sufficient and it seems likely that enabling these kernel build config settings would allow it to work.
