Hi All:
i have met same problem. The ucview default button can't work, so it
can't
set defaults value by defaults button, but OS reboot.
So unplugging and replugging the camera doesn't help ?
i had tried it, but not help.
The information is as below.
[ 104.558118] uvcvideo: Failed to query (129) UVC control 2 (unit 2) : -110
(exp. 2).
[ 104.858153] uvcvideo: Failed to query (129) UVC control 3 (unit 2) : -110
(exp. 2).
[ 104.960430] uvcvideo: Failed to query (129) UVC control 6 (unit 2) : -32
(exp. 2).
Best Regards,
tomsun
