I have same chipset webcam too. It does'nt work.There is two modules in Ubuntu for that webcam.And they conflicts.Temp solution is sudo modprobe -r zc0301 and sudo modprobe -r gspca.Then load gspca again:sudo modprobe gspca. Now webcam should work. Every kernel update i remove /lib/modules/2.6.2x-x-generic/kernel/drivers/media/video/zc0301/zc0301.ko.That is problem still in feisty and gutsy.

Hi, thanks a lot for your bug report, this is being worked on bug #144745 so further development there.

Thanks!
