	the genesys backend supports two gl646 models (MD6471 and HP2300). I have put 
some tools and documentation at http://stef.dev.free.fr/sane/genesys . The 
gl646 ASIC is one of the few for which you can get a pdf documenting its 
registers (search for 'gl646 pdf' to find it).
	Adding support for it doesn't involved deep knowledge in C, but quite some 
trial and error after much time spent gazing at the USB logs.
	Any patch to improve support the genesys backend is welcomed.
