I recommend that you post this on the SANE mailing list 
(http://www.sane-project.org/), as this is a scanning problem. I am 
CCing this posting to there.

AFAIK noone has written a driver for scanner buttons yet (also not for 
other scanner models). The scanner probably sends a certain signal 
through the USB which is caught by a background process under Windows. 
This process then starts a program to do the scan. The best way to write 
a similar program under Linux is to use a USB sniffer to analyze how the 
signal looks like and then write a daemon which listens for such signals.
