Just a quick update, I had to take a little time off from the project 
but I should be able to work on it more now. I have an update at 
http://sites.google.com/site/bez625/updates-1/update with new log files 
for smaller scan and preview snoops.

Stef is there any chance you could explain the layout of your script to 
me a little, for instance

URB  7278  control  0xc0 0x0c 0x8e 0x20 len     1 read  0x01

I take it this means:

URB <URB Num> <URB Type> <4 hex values> len <Length> <r/w> <data>

What are the 4 hex values for? Also anything else helpful will be 
appreciated. I'm not certain how I can better find the values I need for 
genesys_devices.c, I look for the hex values of the registers that need 
to be set and cant find them in the new reduced log files. Maybe some of
these values are only set at power up and not before a scan or preview?
