I can't provide a complete answer at this point, but here's what I know so far about camera support under WSL2:
<ul>
<li>You have the first step correct by sharing the camera via USB/IP, but that's unfortunately only part of the process.
</li>
<li>WSL2's kernel does not include any media drivers by default either, so you'll definitely need to add those to your kernel:
<pre><code>sudo apt install build-essential flex bison dwarves libssl-dev libelf-dev 
libncurses-dev
mkdir ~/src
cd ~/src
git clone --depth=1 https://github.com/microsoft/WSL2-Linu
x-Kernel.git
make KCONFIG_CONFIG=Microsoft/config-wsl menuconfig
</code></pre>
Enable the following options. All should be enabled as built-in, not modules. The option should have an &quot;*&quot; next to it rather than an &quot;M&quot;:
<ul>
<li>Select Device Drivers -&gt; Enable Multimedia support
</li>
<li>Select Multimedia support -&gt; Media Drivers: Enable Media USB Adapters
</li>
<li>Select Media USB Adapters: Enable USB Video Class (UVC)
</li>
<li>Save the config to &quot;Microsoft/config-wsl.uvc&quot; (or whatever you want to call it)
</li>
<li>Exit menuconfig
</li>
</ul>
<pre><code>make KCONFIG_CONFIG=Microsoft/config-wsl.uvc
</code></pre>
<ul>
<li>(A bit fuzzy on the details here since it's been a few weeks since I did it) Copy the platform <code>bzImage</code> to a location on your Windows drive.
</li>
<li>Update the <code>.wslconfig</code> file in your Windows user profile directory to point to the new kernel (see <a href="https://learn.microsoft.com/en-us/windows/wsl/wsl-config#configuration-setting-for-wslconfig" rel="nofollow noreferrer">here</a> for starters).
</li>
<li><code>wsl --shutdown</code> and restart to load the new kernel
</li>
<li>Confirm it is in play with <code>uname -a</code>
</li>
<li>Still working on this part, but it seems to help if you disable the device driver for the camera in Windows. Otherwise Linux and Windows will be fighting for control.
</li>
</ul>
</li>
</ul>
Even with all that in place, I have not been able to capture video yet. I can at least get the camera to show up in WSL2 after that as evidenced with <code>v4l2-ctl --list-devices</code>.
Hope that helps you at least make some progress. I'd be interested in knowing if you solve it completely.

I have followed this tutorial: <a href="https://github.com/dorssel/usbipd-win/wiki/WSL-support#usbip-client-tools" rel="nofollow noreferrer">https://github.com/dorssel/usbipd-win/wiki/WSL-support#usbip-client-tools</a>
I successfully connect my USB camera with my WSL2, but can not open the camera.
<pre><code>$lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 046d:08cb Logitech, Inc. Mic (Notebooks Pro)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
</code></pre>
My camera USB is Logitech, Inc. Mic (Notebooks Pro) and my program:
<pre><code>import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while(True):

 ret, frame = cap.read()
 if ret:

 gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

 cv2.imshow('frame',gray)
 if cv2.waitKey(1) &amp; 0xFF == ord('q'):
 break
 else:
 break
cap.release()
cv2.destroyAllWindows()
</code></pre>
it shows
<pre><code>[ WARN:0@0.009] global /io/opencv/modules/videoio/src/cap_v4l.cpp (889) open VIDEOIO(V4L2:/dev/video0): can't open camera by index
</code></pre>
I’ve used v4l-utils to query my container’s video devices
<pre><code>v4l2-ctl --list-devices
Failed to open /dev/video0: No such file or directory
</code></pre>
I have added some config in Device Driver like @NotTheDr01ds said and now my camera show up in WSL2 with command
<pre><code>v4l2-ctl --list-devices
UVC Camera (046d:08c9) (usb-vhci_hcd.0-1):
 /dev/video0
 /dev/video1
</code></pre>
But when I tried to run my program, its showed
<pre><code>[ WARN:0@10.310] global /io/opencv/modules/videoio/src/cap_v4l.cpp (1000) tryIoctl VIDEOIO(V4L2:/dev/video0): select() timeout.
</code></pre>
The light of camera is on but can not capture anything. I have tried these command below:
<pre><code>lsmod
rmmod uvcvideo
modprobe uvcvideo nodrop=1 timeout=5000
</code></pre>
but its showed error
<pre><code>rmmod uvcvideo
rmmod: ERROR: Module uvcvideo is builtin.
</code></pre>
I have not find any solutions yet. Any suggestion??
