	you may search the archive about mails for HP 2400 support. The answer is the 
same. Basically, the process is to record USB logs of the scanner working 
under windows, then process them to extract commands and register settings, 
then modify the genesys_gl646.c code to handle it the same. There is some 
documentation at http://stef.dev.free.fr/sane/genesys/index.html . The C code 
involved is not high, all you'll have to do some modification of existing 
	There is allready an device description of the 3670c in genesys_devices.c . 
To do a quick test, you can uncomment (remove the '#' at the start of the 
line) the usb id of your scanner in genesys.conf (which is usually located 
at /etc/sane.d), then try to use it from scanimage. It should be detected and 
I expect it to fail during warm-up.
