What is the problem?
Octoprint cannot connect to webcam
What did you already try to solve it?
Know if camera is being recognized by the raspberry
/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
Additional information about your setup (OctoPrint version, OctoPi version, ...)
Last version of Octoprint
Not sure if you have edited the octopi.txt file to use a USB camera vs the default raspberry cam?
Just trying to see what you have done before we get too deep.
