The result you described is more or less how far we've come with this 
scanner when it was first mentioned last year. In the meantime I 
haven't done any work on it.

What I need is a USB trace from a windows scan session to see if any 
command uses different parameters than other other scanners. You can 
get an USB tracer from http://benoit.papillault.free.fr/usbsnoop/, 
the page also gives some instructions on how to use it. The scan 
session should contain an preview scan and a "real" scan of a small 
area at lowest resolution.

The traces tend to become very large, so please gzip with highest 
compression rate before sending.

Regards,

Oliver
