Sharing a USB camera with usbipd in a docker container

[guillaumenibert]

Hello everyone, thank your for your work, I am looking to share my USB camera to a docker container.
Based on discussion #315, I performed these steps:

• I recompiled the Linux kernel for WSL with camera driver support,
• then attached my camera to WSL using usbipd,
• tested the camera on the Ubuntu default WSL distribution with cheese: it works.
• /dev/video0 is visible in the docker-desktop distro, but not in the container:

I tried this tip (#315) from @NikLeberg:

Hi @salvatoreTorsello I use usbipd successfully to forward a USB device to a docker container. For that I had to map -v /dev:/dev and add --privileged so the container can access the devices. Depending on you device you have to install drivers for it in WSL2 thought.

Adapting it, I tried these configurations (docker compose file), with or without privileges, with or without the devices part,

...
privileged: true
volumes:
   - /dev:/dev
   - /run/desktop/dev:/dev
   - /run/desktop/dev/video0:/dev/video0

devices:
   - /dev:/dev
   - /run/desktop/dev:/dev
   - /dev/video0:/dev/video0
...

When I do lsudb in my container, the camera is visible, but the output of ls /dev does not list video0.

I am interested in any advice, whether or not it concerns usbipd or rather WSL/Docker.

Best regards,

Guillaume
