Cannot find my webcam

Support
1

Greetings!

For starters, I am new to using Linux, so I am sure I’ve not done all I can do to fix this problem.

have recently tried to use a webcam after plugging it into my system but when I try to add it via the camera configuration it’s not showing up, when I use the lsub command it is showing up in the list, but when I use dmesg | tail I am getting the following output:

Hi there,
You need sudo for dmesg.

I looked into the correct driver I need for that particular webcam (took some time, but the information I found on the arch wiki was quite helpful)

Just had to look up a particular driver and then install it with the information that the arch wiki gave, after installing it everything worked fine.

Hope it helps.

Could you share what you did in detail? There is a thread active right now where people are talking about problems with this webcam model and the latest kernel versions:
www forum manjaro org/t/webcam-does-not-work-on-kernel-4-19-223-under-ubuntu-14-4-to-20-4-it-was-no-problem/
(I’m not allowed to share links… :frowning:)

I also came here because I own such a system, and while it works fine on other computers (including Arch Linux), it doesn’t work out of the box on Manjaro.

Hi there, first off apologies for the late response I’ve been at school.

Secondly I can really only link the arch wiki as I used that to find the driver I needed and after that it worked just fine, and since I am really new to Linux I don’t wanna give the wrong information. All I can really do is link the Arch wiki sadly.

Regardless I do hope this will help you at least a little bit.
