USB Camera disconnects from raspberry pi #38

Closed necrosato closed 5 years ago

necrosato commented 5 years ago

After running the main server for a few days with a logitech c270 webcam, the webcam randomly disconnects and /dev/video0 disappears. Related to https://www.raspberrypi.org/forums/viewtopic.php?t=40551

This can be fixed by using a powered hub (I think?) or using a raspberry pi camera. (Ribbon cable connected)

This is causing even worse problems. When the camera disconnects, there are so many logs that the logs take up 100% of the disk space. 🤦‍♂️

I now have reason to believe it is due to a faulty power supply. Swapped it out and have yet to see the issue. See https://lb.raspberrypi.org/forums/viewtopic.php?t=210914. Closing until proven otherwise.

Of course, hours after I close the issue, it happens again. @#*$

So far I have not encountered problems with my webcam (Logitech C200). Refer to this list of webcams and opt for the ones that say "works fine without powered hub".
