Logitech C922 webcam not detected on Ubuntu 18.04LTS

Question

I just got a Logitech C922x (USB) webcam which I need to install on Ubuntu 18.04 LTS.

I tried on Cheese and on Skype, but it says that the device is not detected.

Any idea? Thanks a lot for your help.

When I type journalctl --follow in the Terminal and plug in the USB webcam, it says:

Solution

I manage to get it to work by plugging the Webcam into a USB 3 port directly on the computer (not using a usb hub or any other intermediate) and then rebooting the computer. Cheers (Works on Ubuntu 18.04LTS and 18.10)

Try typing alsamixer in your Terminal and rising all inputs. Also before this, did you check the input source in your Ubuntu System Settings?
