	Hello,

	I have added device entry for your scanner in the genesys backend, as a 
clone of the G4050. If you compile and test, don"t forget that install 
procedure doesn't update already installed conf file such as genesys.conf. You 
have to do it manually. The scanner may be tested without doing 'make install' 
with the apended script which must be run from within the 'backend' source 
subdirectory.

Regards,
	Stef
