Ciao!
I'm davide from italy (sorry for the grammar),
and i'm trying to activate the webcam Z-Star with the "Jef Moine" driver: gspcav2-2.0.3 <http://moinejf.free.fr/gspcav2-2.0.3.tar.gz>
on the website it seems to work..
The drivers compilation and installation goes well,
the modules loading too,
but the webcam seems doesn't work :-(
I also have a webcam with the same USB ID, although the dmesg is a little different:
[ 440.583088] usb 2-2: new full speed USB device using uhci_hcd and address 2
[ 440.654956] usb 2-2: configuration #1 chosen from 1 choice

Maybe you can try the mplayer line that works with me, after plugging in your webcam:
mplayer -cache 128 -tv driver=v4l2:width=640:height=480:norm=PAL:outfmt=i420:device=/dev/video0 -fps 20 -vo x11 -vc rawi420 tv://
Best regards,
