Scanning as user?

Hello list,

after a 'insmod advansys' command in '/etc/init.d/boot.local' the 
Advansys-Card works (as 'cdrecord --scanbus' shows). That's allright. 

But if i want to work with the scanner, i have to "install" the scanner with 
YAST -> Hardware -> scanner as ROOT (immediatly after YAST -> Hardware -> 
scanner YAST shows the right scanner as 'installed' - strange, but that the 
fact). After that i (as USER) can use the scanner by GIMP. Shutting down the 
system there is the message: 'Resetting /dev/sg3' (or similar text - /dev/sg3 
is the scanner) and after the next boot i have to "install" the scanner 
again.

What i have to do, if i want to use the scanner as user (maybe) by booting the 
system? And is there a way to pre-install the scanner? YAST or the system 
seems to loose the settings while shutting down.

best regards,

Chris
