Using the Easycap USB video capture device with Debian Slug
Notes for next time

I first needed to update my Debian nslu2 from Etch to Lenny

The Easycap Linux driver source code is here
and I compiled it as in the source README

I needed mjpg_player which can stream the pictures to a web page
I compiled mjpg_player from source - odd that you can't apt-get it
ln /dev/easycap0 /dev/video9

My path to mjpg-streamer was /home/graham/mjpg-streamer/mjpg-streamer/mjpg_streamer
So to start it I did

/home/graham/mjpg-streamer/mjpg-streamer/mjpg_streamer -i "/home/graham/mjpg-streamer/mjpg-streamer/plugins/input_uvc/ -d /dev/video9 -f 5 -y -q 80 -n" -o "/home/graham/mjpg-streamer/mjpg-streamer/plugins/output_http/ -p 8070 -w /webcam_www"
