That is a very old kernel version, you should at least upgrade to a
modern one.

Looks like the driver is bound properly to the device, are you sure this
device follows the correct UVC specification?

Try updating to a 5.9 kernel version, and if that doesn't work, send
your log message to the linux-media developers, they can help you out
better than we can.

good luck!
