Given that this seems to be a problem with "uvcvideo" itself, you are probably best of by talking to the developers of uvcvideo, which would be:
[johnpatcher@vpcs linux-3.7]$ ./scripts/get_maintainer.pl -f drivers/media/usb/uvc/uvcvideo.h Laurent Pinchart laurent.pinchart@ideasonboard.com (maintainer:USB VIDEO CLASS) Mauro Carvalho Chehab mchehab@infradead.org (maintainer:MEDIA INPUT INFRA...) linux-media@vger.kernel.org (open list:USB VIDEO CLASS) linux-kernel@vger.kernel.org (open list)
See [1] for linux-media.
Best regards, Karol Babioch

Try creating /etc/modprobe.d/uvcvideo.conf and put this inside: options uvcvideo nodrop=1
Then as root do: modprobe -r uvcvideo && modprobe uvcvideo
or alternatively reboot. Then try again.
