Hello,
Using an Acer 7551-7442 here with the following built-in webcam:
Bus 002 Device 004: ID 0402:9665 ALi Corp. Gateway Webcam
It seems motion locks up every day or so and I see this in the kernel logs:
[378982.724053] uvcvideo: Failed to resubmit video URB (-27).
[378982.724066] uvcvideo: Failed to resubmit video URB (-27).
[378982.724079] uvcvideo: Failed to resubmit video URB (-27).
[378982.724090] uvcvideo: Failed to resubmit video URB (-27).
[378982.724101] uvcvideo: Failed to resubmit video URB (-27).
[489148.723367] uvcvideo: Failed to resubmit video URB (-27).
[489148.723379] uvcvideo: Failed to resubmit video URB (-27).
[489148.723391] uvcvideo: Failed to resubmit video URB (-27).
[489148.723403] uvcvideo: Failed to resubmit video URB (-27).
[489148.723414] uvcvideo: Failed to resubmit video URB (-27).
If I restart motion, it will usually start working again, I do not
have this problem on other (retail) Logitech webcams, was curious if
this a bug with the webcam (quirk?) or a problem in uvcvideo?
The camera is built-into the laptop screen at the top in the middle.
