Hi,
I have my logitech sphere up and running with a 64 bit 3.0 kernel.
All controls are working including pan/tilt/ and focus.
In ubuntu at least you can't cold plug the camera, or uvcdynctrl won't
get triggered.
The easiest way is just to rmmod and then modprobe uvcvideo, this will
get everything working.
At least for me it did.
Regards,
Paulo
