Camera model
C920
added new generic usb cam
What is the problem?
after adding a cam
randomly camera are working or not
4 cases:
c920 working, generic not
c920 not working, generic work
they both work
non of them work
What did you already try to solve it?
run cat /var/log/messages
according to this i think when cameras are at video0/video2 they work
on video1/video2 they don't
i mean i already set 99-usb.rules for the camera and it's working
but on log it's looking like it assigning video0-3
(can i assign the video0-3 myself?)
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
from a case when c920(video0) worked and generic(video3) not:
