Hi,
I got an issue with video(4)/uvideo(4). If,
during bootup or at any point in time after
that, I move the lid of my notebook I get
the following messages:
video0 detached
uvideo0 detached
and the webcam stops working.
This is for quite some time now and I thought of
it as an hardware issue and my fault as it came
after I opened the machine to exchange my wireless
card.
But, after I played a bit with suspend and resume,
I encountered this on resume:
uvideo0 at uhub0
port 5 configuration 1 interface 0 "Sonix Technology Co., Ltd. USB 2.0 Camera"
rev 2.00/1.00 addr 2
video0 at uvideo0
and the webcam is working again.
Important: I did not touch or move the lid after
the detachment messages above!
This works reliably. If I move the lid again
it detaches and I can suspend/resume to get
it back again. It does not come back without
suspend/resume though.
I did not file a bug report through sendbug(1)
yet as I am still not confident that this is
not a hardware issue.
Any ideas or thoughts on this?
