Public bug reported:
The webcam on my Acer Aspire 5920G doesn't work properly- when starting
the camera using Ekiga or Cheese or luvcview, initially all looks well.
However, after a few seconds (usually between 5 and 20) the camera
stops, with the window displaying a corrupted image. I also observed
this behaviour with another 5920 (not G!).

After the device stops working:
Code:
[CODE]dmesg
[ 521.251212] uvcvideo: Failed to resubmit video URB (-45).
[ 521.251229] uvcvideo: Failed to resubmit video URB (-45).
[ 521.251240] uvcvideo: Failed to resubmit video URB (-45).
[ 521.251249] uvcvideo: Failed to resubmit video URB (-45).[/CODE]
Whichever app I am viewing the webcam with also crashes, and I have to
'Force Quit'.
Ubuntu 8.04.1.
