Webcam setup for dummies

BWWNBY Webcam with Microphone - driverless, works with Linux

What is the problem?
I seem to be missing a piece of the puzzle in getting a webcam working

What did you already try to solve it?
I have read as much as I can understand

Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
/var/log/webcamd.log does not exist
syslog contains no info on apparent "problem"
dmesg contains no info on apparent "problem"

Additional information about your setup (OctoPrint version, OctoPi version, ...)
OrangePi PC+ with Armbian/Octoprint image

lets see what dmesg says when you plug the cam in

disconnect your cam, connect it again, enter dmesg | tail -n 20 and post the output her

also post the output of ls -lah /dev/video*
