Comment 17 for bug 224559

Here is temporary solution as kernel patch: http://forum.ubuntu.ru/index.php?topic=59385.msg438527#msg438527 (sorry, only russian).
Patch applies perfectly on 2.6.30 kernel (may be get from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/) or with one manual edit of uvcvideo.h for earlier kernels.
