Description

I have a small USB camera - it will sometimes attach and work perfectly. Then, after a week or so, it will not show up, or show 'video device not detected' and the gray screen. Sometimes a power cycle will fix it, reboot sometimes as well. Sometimes nothing fixes it and I just give up.... it's a v4l device. I had similar issues before with a different app (motion), so may be a v4l issue.

Contributor guide

Research direction
Investigate the USB camera detection issue by checking dmesg logs, verifying v4l device presence, and testing with v4l utils. Look for patterns of device disappearance and reattachment. Consider kernel module issues or USB power management.
