Hello everyone,
I recently upgraded from a 4.4 kernel to 4.10, and found that my Logitech
Quickcam Sphere now behaves differently.
More specifically, the pan/tilt controls do not work anymore - in fact,
they are completely gone from "v4l2-ctl -L".
In dmesg, I'm getting these messages:
[ 10.129984] uvcvideo: Found UVC 1.00 device <unnamed> (046d:0994)

I suspect that https://bugzilla.kernel.org/show_bug.cgi?id=111291#c10 may
be related, and the new extension handling causes the pan/tilt controls to
disappear.
Question now is, how to get them back?
Best, Florian
