Has anyone tried using spca5xx with 2 webcams?

I'm having a lot of trouble getting both webcams to send an image. 
One is always truncated.

I suspect the spca5xxLE driver, since I can cause the webcams to fail
to read based on the order invoked.  ATM if I initialize /dev/video0
first and /dev/video1 second, then /dev/video0 will provide corrupt
images.  If I reverse the order in which they are initialized, then
the other camera will send corrupt images.

One camera consistently sends the full image, and the other camera
sends only the top 1/5 or so of the image.

Hmmm....

I've posted my very ugly and hacked up version of spcacat at
<http://www.seiner.com/spca.tar.bz2>

You should use the following line:
spcacat -f jpg -g -N 1 -d /dev/video0 -d /dev/video1 -w 7070

and then from a remote machine connect to it:

nc 192.168.128.138 7070 > x.jpg
nc 192.168.128.138 7071 > y.jpg

nc should provide the full image.  Alas, it does not.  It's not a
network problem; the read itself from the driver is short.
