Hi Mauro and Laurent
@Mauro:
I think there is a confusion, which might be my fault as I talked about
a chicony cam in the external monitor. The chicony cam that shows up as
video0/1 is my internal laptop camera which is working fine. The
problematic one is the sunplusIT camera which has a chicony usb
identifier (0412). This is connected to video2-5 and also the one for
which I reported the above information.
