HP VGA cam.

I'm trying to write a driver for the HP VGA camera. USB ID: 15b8:6002. 
The sensor is 7131r, and the bridge is probably vc0323 (although the inf 
says it's vc0326). It's inf is the same inf which includes the po1200 
sensor, which was added in December last year (The HP 2.0 Megapixel 
camera). I am trying to use usbsnoop in a windows installation, but the 
log size just does not cease to come to a halt (as is specified in the 
microdia site), thereby leaving me unable to snoop the init sequence. 
What might be wrong?

Also, is this the same sensor as hv7131r, as in vc032x.c?
