	If you wish, I can provide you with my awk scripts that turn usb logs into 
low/mid level genesys functions. Which ease the developpement. 
	I'd recommend to play with sane 1.016 sources, since the experimental version 
is now not working any more for hp2300/md6471 due to some exposure_time 
improvement. When this will be resolved, you may bring back you change into 
it.
	The code path to modifiy is the one taken by th hp2300 (look fo HP2300) in 
code. You'll have to figure how the  right register related constants to put 
into genesys_devices.c .
