Can anyone help me to configure the following for Redhat 7.2 ?

A Benq/Acer 3300 u (USB scanner)

I deleted an earlier sane and installed backend and frontends 1.0.8
I didn't install Xsane yet.

I can't get sane-find-scanner to find anything
Same problem with scanimage -L
I've tried a lot of things

What should I check? Please list as many as possible.
I think the USB setup may need fine tuning.
I can insttall ausb module using insmod scanner and get :

[root@localhost root]# insmod scanner
Using /lib/modules/2.4.7-10/kernel/drivers/usb/scanner.o

I think I installed firmware (2 binary file posibilities and 2 possibilities 
for vendor and user ID numbers but one particular pair of numbers is detected 
by the system. I edited the snapscan.con file to point to the firmware binary.

I also did the following:

       When  using  a USB scanner, ensure that the access permis­
       sions for the USB device are set appropriately.  We recom­
       mend to add a group "scanner" to /etc/group which contains
       all users that should have access  to  the  scanner.   The
       permission of the device should then be set to allow group
       read and write access.  For example, if the scanner is  at
       USB  device /dev/usb/scanner0, then the following two com­
       mands would set the permission correctly:

              $ chgrp scanner /dev/usb/scanner0
              $ chmod 660 /dev/usb/scanner0

	 The system detects it 
I have detected a uhci based controller but think more configuration may be 
needed here.
Should I use dev/ttyUSB0 or /dev/usb/scanner0  ?? Does it matter?

Any advice would be most welcome before I go Insane.
What should I check or do?
