Re: [SOLVED] My webcam is not working, i have tried everything to solve it

Well, as the revert is not in the 6.13 kernel, (just found out by updating by mistake to 6.13) and it seems not to be in 6.14. I would like to ask, - is there an intention at all to revert the problem for some webcams? What is the harm by letting those webcams slip thru the id checking.

Re: [SOLVED] My webcam is not working, i have tried everything to solve it

For what it's worth: After hours of searching and testing, I found that those camera problems don't belong to all cameras, but to specific models. In my case it's the "ID 1b3f:2002 Generalplus Technology Inc. 808 Camera". It worked out of the box, but now it's not recognized anymore. Another camera the
"ID 0471:0308 Philips (or NXP) PCVC680K Webcam [pwc]" still works fine. Anybody got an idea?

I have the same cheap chinese device. It worked flawless. No change in the kernel drivers/firmware. As I'm now the third user with the same observation, my best guess would be
Hardware defect

It's not hardware defect, i have the same problem, the camera works on Windows, works on Mac and worked on Linux before the kernel update. I'm using the Linux 6.12.1 until they fix this problem.

My camera is: Bus 007 Device 002: ID 1b3f:2247 Generalplus Technology Inc. GENERAL WEBCAM

Can you reproduce the issue using 6.13.3.arch1-1 which contains 69d44bc Revert "media: uvcvideo: Require entities to have a non-zero unique ID"?

I have the same problem, but I'm already on

and the webcam still doesn't work. It does work with the

sudo pacman -U linux-6.12.7.arch1-1.1-x86_64.pkg.tar.zst linux-headers-6.12.7.arch1-1.1-x86_64.pkg.tar.zst

command.
