The quickcam module I used to see loaded with the early versions of the 
driver that you'll find from my sourceforge reference was quickcam.o 
It's likely that's the one that's loading.  I've actually got olde 
source from two different versions of that driver, you're welcome to 
them if you'd like to try them, but I'd suspect the version found at 
sourceforge would be a better solution.

I'm not sure what 'error = 256' means, but that dev major/minor 
corresponds to /dev/video0 on my box.  Is it possible you don't have 
perms to use it?  Try it as root?

I don't know if that was a good idea. :(

That looks promising.  Did you get it before?

That would seem to have been caused by your previous removal, you might 
recreate those devices and try it as root.

So here you're saying the device does exist?  Hmmm, this is confusing to 
me.  I would have expected that error would have been a perm error, not 
a 'no such device' error.  Try running it as root?
