[Robert.L.Harris@rdlg.net: 2.6.6 and Philips web cam]

[Robert L. Harris]

I sent this to the owner of the PWCX drivers and no-answer so I'm hoping
someone here might have an idea.  Yes, I tried using the 2.6.4 kernel
with the exaxt same results as the 2.6.7 kernel (output below is from
2.6.7).


------------

I just got a new machine and it's doing the same thing so I figure it's
not hardware.  Basically when I run camstream it complains about an IO
error and blows out.  Here's the console output of camstream:
