Regression: active uvcvideo breaks over suspend

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I found this in v2.6.30-rc2. I haven't tested beyond that. I'm sure it didn't happen in 2.6.29.

If I run "xawtv" and then suspend, it stops working on resume; the xawtv display goes black and the camera LED stays off. When I close xawtv, the LED blinks on then off again. If I then try to run xawtv again, it works fine.

In dmesg (after resume) I see

[  562.884298] usb 1-8: type resume
[ 562.990014] usb 1-8: reset high speed USB device using ehci_hcd and address 3

Thanks in advance
