Hi,
I am using a new Logitech C910 usb webcam plugged into an OMAP3530
embedded board using Kernel 2.6.32
Getting this error after a period of correct operation:
[ 2890.610992] uvcvideo: Failed to query (135) UVC control 2 (unit 2) : -110 (exp. 2).
[ 2890.939117] uvcvideo: Failed to query (135) UVC control 2 (unit 2) : -110 (exp. 2).

[ 2893.235992] uvcvideo: Failed to query (135) UVC control 1 (unit 2) : -110 (exp. 2).
The only way to bring it back - that I have found so far - is a system reboot.
Other USB devices connected to the same controller do not work after the camera fails which indicates a controller crash?
I have tried 6 other cameras that all have the same issue.
I have been talking with Laurent Pinchart who maintains the UVC driver for Linux who suggested I contact the USB mailing list.
Any ideas on a possible solution?
Regards,
CJ
