Had a few problems with this webcam myself, took me awhile to get it to work. Heres what I did:
Code:
locate pwc.ko
sudo rm <path to files above>
wget http://www.saillard.org/linux/pwc/files/pwc-10.0.7a.tar.bz2
tar xjf pwc-10.0.7a.tar.bz2
cd pwc-10.0.7a
make
sudo make install
rmmod pwc pwcx
depmod -a
modprobe pwc power_save=1

Then just open up your favourite cam viewing program (eg. camstream, xawtv).
