	Hello,

	the HP2400/G2410 (G2410 is a re-badged HP2400 to my knowledge) support in the 
genesys backend is still experimental since I lacke this hardware. However, I 
have set up color modes for 50, 300 and 600 dpi based on USB logs sniffed 
under windows. So it would be nice if you could test the latest sources 
version of SANE with your scanner at 50 dpi color.
	To test you'll have to get the sources like explained at http://www.sane-
project.org/source.html . Once you have compiled them, put the attached run-
hp2400 script to sane-backends/backend source directory, open a command shell 
and go to this directory. Then run it, it'll test a 50 dpi color scan and 
creates a hp2500-scan.pnm and hp2400-scan.log files. Let us know the result. 
In case it doesn't work, please send these files.

Regards,
	Stef
