compiled it with module-assistant. Everything went ok, and modprobe

Relevant modules loaded are:
spca5xx
videodev

v4l2-common
usbcore



I don't know much, but how are you accessing the camera? what if you
do a

cat /dev/video[0] > testvid

does that cause a freeze?

if not, can you play that file in mplayer or xine or whatever?

this method sometimes works with tuner cards for example just to see
if the thing is working. I just tried it with my webcam and it didn't
really work, in that I got no playable video (probably due to
compression), but at least it shows that there is info coming from the
camera.




Other people seem to be using this webcam model quite successfully, with
various distros, so I believe its some troubleshootable thing which I am
missing badly.
Someone help?




I think that you can get spca5xx binaries from debian, its the gspca
that needs compiling... at least in sid its spca5xx-modules-<kernel>




Hi andrew,
I tested the camera with the utility from the driver author, spcaview
and spcagui. Cat'ing /dev/video1 (video0 is a bttv card) froze the
machine just the same.

So, the problem is with the driver?

sounds like it. using cat pretty much eliminates everything but the
drivers from the chain. but maybe you are conflicting with the bttv
card? can you pull the tv card and try it? maybe you have conflicting
interrupts? as I said before, have you tried the binary modules from
debian ?
