Hi, using regular fedora (43) on a desktop comptuer with a USB webcam. Worked fine after installing the OS last year but a recent update (last 2-3 weeks i think) has stopped the camera from showing up as a video source. It does appear as a microphone and seems to work fine.
I did some digging but am clueless about making it work again as it was fine out of the box. Here’s some diagnostic outputs other people suggested:
v4l2-ctl --list-devices
HD Pro Webcam C920 (usb-0000:25:00.3-3):
/dev/video0
/dev/video1
/dev/media0
Unplugging and repluging it in doesn’t help, here’s the dmesg output from that:
[ 220.603579] usb 5-3: USB disconnect, device number 3
