What is the status of using the zed sdk 4.1.1 in wsl 2.0? I tried using the docker image for Ubuntu 22.04, and using usbipd, lsusb sees both the camera and the hid, but when running the container, no camera is detected. When I checked /etc/udev/udev.conf in the docker container, I didn’t see any sl specific entries.
Thanks!
Does it work if you manually add the required udev rule?
Thanks for the quick reply!!! What is the required udev rule and I will try that.
This one
99-slabs.rules (4.6 KB)
it must be located in /etc/udev/rules.d/
Ok, I added that to the container (and restarted the container), and the camera was still not detected. I also added it to the wsl ubuntu /etc/… and still no luck.
Please run ZED Diagnostic and send the report file that it generates
Ok, I will need to build a container that has the sdk because the docker image from dockerhub does not include the tools (I was surprised at that).
Thanks as always for your help.

Can you try to open the camera with cheese or guvcview to verify that the RGB stream is available?
Thanks for the suggestion. Using cheese inside the container or outside the container results in the same No Device Found, even though lsusb sees the 2 devices.

This means that the UVC driver of the virtual machine is not working as expected.
Unfortunately, I cannot help you fix this type of Ubuntu problem.
Please try to search the internet to find a suitable solution for WSL2.
Yes, I think that I will need to rebuild the kernel, so outside your scope.
It would be good for stereolabs to have a support page on using the camera in wsl since this does keep coming up, even if it is a link to instructions on how to rebuild the kernel.
Thanks again for being so responsive.

So… I followed the directions in this Medium post: wsl2-webcam (https://medium.com/software-dev-explore/wsl2-webcam-23c1dc9408ae ) to rebuild the wsl kernel. As someone else has said, it is straightforward if you follow the directions. Once I rebuilt the kernel per the instructions, I was able to use v4l2, so the video stream is working now (you still have to do the usbipd stuff). So progress.
I now am having USB issues with the device. I have attached the report from Diagnostics. Any ideas?

Hi,
I guess now the problem is related to udev.
The SDK cannot access the HID device and reports a USB error.
