	Hello,

	the working version is available as source code. There are ubuntu PPA 
that provide packages for it. The 2 first hits at 
https://launchpad.net/ubuntu/+ppas?name_filter=sane seem rather promising for 
you.
	In case you have still troubles having your scanner with these packages,
please send the debug.log file generated by:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
scanimage -d genesys >scan.pnm 2>debug.log

Regards,
	Stef
