Welcome to the Hailo Community!

You need to check whether your USB camera support video4linux short v4l2.

You should see your camera in the /dev/ directory.

ls /dev/video*

Plug the camera in and out to see the difference in case there are many video devices.

Then you can use the v4l2-ctl tool to get further information.

v4l2-ctl -D -d /dev/video0

This should print something like this:

Try another USB camera if you do not get this.

I am having the same issue.

I can see the driver info described above, but I’am getting an ERROR: *** no cameras available *** when running rpicam-apps commands. My Logitech 925e camera works fine with Cheese app.

Is Hailo-8L using the libcamera library only? Libcamera does not seem to work with USB cameras.

ok nevermind, it seems to work now on usb webcamera.

I followed the guide on github hailo-ai/hailo-rpi5-examples/
