I have the C922 Pro here too, but it does not work well with my ubuntu21.04
sometimes it could be recognized by the os, but for most time it could not be recognized with message in dmesg like this, not sure if you have any idea what's the problem there.
I suspect that the webcam needs more power to start, and my laptop or the usb hub could not supply that much.
but I don't know how to confirm that, and when I use it with one usb hub with external power cable plugged in, it could not work stably too.
the MaxPower is 500mA from the output of the "lsusb -v" command when it works

Hi, JasKinasisAnd if it comes to getting a new webcam - as long as it is UVC compatible - it should work under Linux.
I recently got myself a Logitech c922 pro-stream web cam. Which has built in microphones. It works flawlessly for me in Debian 10 for live-streaming, video chat and photo applications. So I can definitely recommend one of those!
I have the C922 Pro here too, but it does not work well with my ubuntu21.04
sometimes it could be recognized by the os, but for most time it could not be recognized with message in dmesg like this, not sure if you have any idea what's the problem there.
I suspect that the webcam needs more power to start, and my laptop or the usb hub could not supply that much.
but I don't know how to confirm that, and when I use it with one usb hub with external power cable plugged in, it could not work stably too.
the MaxPower is 500mA from the output of the "lsusb -v" command when it works
