Of course it is.

the dmesg during the insmod:


nw802.c: nw802_probe(...)
nw802.c: Compatible DivIO NW80x based webcam found ! [Mustek WCam 300 /
PCLine PCL-W300] nw802.c: Number of alternate settings : 8
nw802.c: Active setting=1 maxPS=960
usbvideo.c: nw802 on /dev/video0: canvas=320x240 videosize=320x240
nw802.c: Module loaded

with xawtv launched (same debug as before), I got nearly 64 lines every
seconds in the desmg like this:

Mar 24 09:20:19 poseidon kernel: nw802.c: nw802_processIsocData
Mar 24 09:20:19 poseidon kernel: nw802.c: Frame ready for decoding

I think this is ok :(

Do you think an usb sniff under Windows can help ?
