Comment 20 for bug 984603

I encountered this bug and, with the much-appreciated help of Hans de Goede, managed to fix it within the stock 12.04 kernel by cherry-picking some patches from the gspca git tree. I went here

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=history;f=drivers/media/video/gspca/zc3xx.c

and applied all the patches up to and including

[media] gspca_zc3xx: Disable the highest quality setting

but skipping over

[media] gspca: Fix locking issues related to suspend

This compiled and inserted without problems in the stock 12.04 kernel, and fixed the bug I was seeing with Skype. Maybe the Ubuntu maintainers will consider a backport?
