Can't get USB webcam to work

Camera model
Generic, this camera worked on a previous OctoPrint on a different Raspberry Pi

What is the problem?
I can't get the video to show up on OctoPrint, and I can't get any of the diagnostics I've seen to show me anything.
I've also tried a Logitech Brio with the same results.

What did you already try to solve it?
I've read topics here, and tried various options in the config files, octopi.txt (10.0 KB)

Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)

Additional information about your setup (OctoPrint version, OctoPi version, ...)
OctoPrint V 1.8.6
OctoPi Version 0.18.0, running on Raspberry Pi 4 Model B Rev 1.4

  • open a linux shell session using a tool like putty,and log in to the Pi
  • unplug the webcam
  • run sudo dmesg -w

you should see info on the webcam appear.

Copy and paste that as a reply.
