	Hello,

	this is correct. SANE searches for conf files in the current working 
directory, then in the configured --sysconfdir directory (in this case 
/usr/local/etc). So copy your modified genesys.conf file in the directory 
where you run scanimage from, or in /usr/local/etc, since 'make install' 
doesn't override already installed configuration file that may miss the device 
you added.

Regards,
	Stef
