I use it once in a while with an old Dlink dsb-c100 camera that I bought for $10 years ago.

I thought the picture was fuzzy, out-of-focus and hard to look at but then I realized that was just the way I looked.

Have you downloaded GQCam from MyDSL and tried the camera with that? If you can get it working with GQCam then it's just a config problem in motion.

I thought the Philips series of webcams were suppose to work OK.

I know the logitech series of webcams need the spca5xx driver that dsl doesn't have. There's an interesting page over at the < Ubuntu Forum > that talks about compiling the driver if someone is adventurous.

Have you looked around on the < Motion Home Page > to see if there is anything about your camera?

-Good luck

Update on webcam installation on Mdk 10.0.

I finally got a Logitech quickcam 4000 pro working. The steps I
did is outlined below.
I haven't figured out how to get the microphone on the cam to
work yet. I don't know what audio module I need to load to get
the USB audio class properly registered but the webcam
works fine in 640x480 resolution at 15 fps.

The main issue I had was that the pwc module that
was shipped with the Mdk 10.0 distribution and whas loaded
when I first plugged in the camera did not work. Apparently
I needed som extra compression module that was not included.
The development of the Philips pwc driver has been
transferred over from Nemosoft to
< http://saillard.org/linux/pwc/files/ >
and the new version does not need the separate pwcx
decompression module.

I downloaded the pwc-10.0.4.tar.bz2 package and
compiled it and removed the old driver:
# rm /lib/modules/2.6.3-7mdk/kernel/drivers/usb/media/pwc.ko.gz
# cp pwc.ko /lib/modules/2.6.3-7mdk/kernel/drivers/usb/media/
# depmod -a
# rmmod pwc
# rmmod pwcx
# modprobe pwc

and the camera worked on the fly, tried xawtv and camstream

Quote end.
As DSL_OS is kernel 2.4.x we should try to compile a module for it. If I had some more time I'd do it. Let's see.
