[AG-TECH] Logitech QuickCam 3000 Pro

Howdy, 

I'm wondering if anybody has had experience in getting the Logitech
QuickCam 3000 Pro to work with vic on a Linux machine.  Here's
what I'm using

RedHat 7.3 (kernel 2.4.18-3)
vic 2.8ucl-1.1.3-AG 

I followed some great instructions, available at

    http://www.isthe.com/chongo/tech/comp/pwc/rh7.3.html

for setting it all up, culminating in the use of "camstream"
to test the drivers and camera, and all worked - I'm able
to capture images from the web cam.

However, when I try to capture these using vic, the camera and all
is recognized but, when I try to actually TRANSMIT via the Logictech
camera, I get a bunch of ioctl errors indicating incorrect parameters
being used.  Appended to this message is the output of running vic.

As you can see, vic finds both the Hauppauge and assigns to 
/dev/video0 and the Logitech and assigns to /dev/video1.
The Logitech USB cam is selected in my device and then I try
to transmit - A thumbnail appears in vic, but with no image, then
I start getting all the ioctl invalid argument errors.  I've played
with virtually every button on vic, and I've even played around a lot
with arguments to the pwc module using documentation from

      http://www.smcc.demon.nl/webcam/install.html#param

However, it's been mostly trial and error with no real knowledge of
what I'm doing.  Is anybody familiar with these issues?  It appears to
me that vic is supplying arguments that either the kernel or, more
likely, one of the loadable modules (pwc) can't quite deal with????

Thanks,

Don
