** Description changed: We have two cameras connected to Cam Link 4K and using OBS for live- streaming. Suddenly during the live-stream the video input went to black. The kernel message shows that the USB disconnect at 2332.127976s (but we did not unplug anything). Some seconds later the kernel shows warnings (2440.834346). Since I did not want to stop the live stream, I unplugged the affected Cam Link 4K and plugged it back in, but this did not help. The video input that was in use when the incident happened kept frozen. At the end, I closed OBS, but a zombie process remained: $ ps auxff | grep ob[s] USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND tontech+ 28535 0.0 0.0 0 0 ?
