Installing open source linux driver for mustek wcam300

download the kernel and compile it folow this tutorial for debian
then get the cvs version of driver

Patch for kernel 2.6 and a Makefile for 2.6. And some small bugg fixes.
So to compile with a 2.6 kernel :

cvs login
cvs -z3
co nw802-2.4
cd nw802-2.4
cp Makefile.26 Makefile
patch -p0 < patch-2.6
make clean

if it fails then go to lists

after kernel compile and driver patching is time for compile

ln -sf /opt/kernel-source-2.6.7/drivers/usb/media/usbvideo.h .
ln -sf /opt/kernel-source-2.6.7/drivers/usb/media/usbvideo.c .
make -C /opt/kernel-source-2.6.7 SUBDIRS=`pwd` modules
make[1]: Entering directory `/opt/kernel-source-2.6.7'
CC [M] /home/mariuz/tmp/nw802-2.4/nw8xx_jpgl.o

LD [M] /home/mariuz/tmp/nw802-2.4/usbvideo.ko
make[1]: Leaving directory `/opt/kernel-source-2.6.7'

then we should do modprobe for driver

su -c 'modprobe videodev'
su -c 'modprobe usbvideo'
su -c 'insmod nw8xx.ko'
dmesg | grep video
Linux video capture interface: v1.00

also at the end of dmesg
nw802.c: Potentially NW8xx supported cam found ( supported vendor/product IDs )
nw802.c: Detected bridge type : DivIO NW802
videodev: "nw802 USB Camera" has no release callback. Please fix your driver for proper sysfs support, see
drivers/usb/media/usbvideo.c: nw802 on /dev/video0: canvas=320x240 videosize=320x240
usbcore: registered new driver nw802
nw802.c: Module loaded

install xawtv
su -c 'apt-get install xawtv'
then you should grap nice movies from your camer :) with this command
xawtv -c /dev/video0
