# Is it possible to get USB camera working with SO101 arm through WSL Ubuntu? > Source: > Published: 2026-07-31 07:25:38+00:00 Hello, I just got a SO101 Arm kit, finished building it and managed to get teleop working. I wanted to continue with the tutorials that are recommended before trying to do anything on my own, but I’ve come to a issue with trying to get cameras working. I have a Logitech C270 usb webcam (wsl passthrough has been enabled), and when running the `lerobot-find-cameras opencv` command I received this error message. I tried a couple things like changing the format to V4L2, but haven’t gotten this command to work as it does in the example. The only thing I found, but probably isn’t what i’m looking for is [`OpenCVCameraConfig` settings fail under `backend=ANY` on Linux; the same settings work with `backend=V4L2` · Issue #3198 · huggingface/lerobot · GitHub](https://github.com/huggingface/lerobot/issues/3198) Thank you Here is the error listed below: ioctl(VIDIOC_QBUF): Bad file descriptor [video4linux2,v4l2 @ 0x5b2d2bd784c0] ioctl(VIDIOC_G_INPUT): Inappropriate ioctl for device -– Detected Cameras — Camera #0: Name: OpenCV Camera @ /dev/video0 Type: OpenCV Id: /dev/video0 Backend api: FFMPEG Default stream profile: Format: 0.0 Fourcc: Width: 640 Height: 480 Fps: 30.0 WARNING:lerobot.cameras.opencv.camera_opencv:Error reading frame in background thread for OpenCVCamera(/dev/video0): OpenCVCamera(/dev/video0) read failed (status=False).
