	Hello,

	nice to have motor moving. Please use git to clone SANE's source tree and 
develop on branch you'll create. So that you'll be able to send patches 
generated by git-format-patch . That'll ease the process.
	Instead of reusing CCD_G4050 entry, create a new CCD_N6310 define and add 
an entry (filling it with G4050 values as a starting point if want, they'll 
have to be changed anyway) to the Sensor[] table in genesys_devices.c . Then 
use it in the device description.
	I use the appended script to reformat the UsbSnoop.log file. I have sent 
several time the 'rl' script I use to run a local test version of the genesys 
backend. It will set up debug messages to the max.
	The first goal is to have uncalibrated color preview (e.g. 75 or 100 dpi 
scan) working.

Regards,
	Stef
