I have a Raspberry Pi Model B Plus Rev 1.2 with a Microsoft Corp. LifeCam HD-3000 connecting running Motion for a Webcam. I am getting periodic errors on the Webcam and it stops working. I am using a 2.5Amp power supply as I was getting low voltage messages but that is all resolved but I am still having problems. Looking at the syslog there are lots of messages/errors but I can't honestly see the wood for the trees. Any help would be gratefully received.

  • which OS/kernel are you running? what are the outputs of lsusb and dmesg when the errors appear? – x29a Sep 22 '19 at 3:47
  • Thank you very much for helping. I have now resolved the issue by upgrading my PI to a 4B with 4GB. From my research it seems that the 4B has better power overall and better USB power management. It now runs for days and weeks without issue. – xh28 Sep 23 '19 at 7:08
