C922 Pro Stream Webcam not detected

Support

I have a fresh install (~ 1 week) of Manjaro Kde Plasma and I can’t get my webcam to work.

# v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.

I’d be glad to go through any troubleshooting steps. Thank you in advance

Hello @nallux :wink:

How is it connected?

lsusb -vt

What’s the verbose output?

sudo lsusb -v -d 046d:085c

Hey @megavolt, thanks for the reply.

It’s connected via USB.

lsusb -vt

sudo lsusb -v -d 046d:085c

this is verbose indeed. I don’t understand what I’m seeing. Here’s the whole output:

hm… no driver has been loaded here.

  1. Unplug the camera.
  2. load the driver:
sudo modprobe -v uvcvideo
  1. Plugin the camera.

Check again if a driver has been targeted: lsusb -vt

Sorry for the late reply, it appears that the driver does not exist

modprobe: FATAL: Module uvcvideo not found in directory /lib/modules/5.15.41-1-MANJARO

What packages would I need to install for this?

None… that is a kernel driver. Looks like you did not reboot after upgrading the kernel. The path has been changed and no new drivers can be loaded.

I can’t believe that it was something so trivial. My webcam works fine now. Thank you!
