I have been using this very AGFA scanner for years in Linux, and it is 
really well supported. But with the 2.6 kernel series, the rationale has 
changed: no more kernel modules or /dev's, bus the scanner is addressed 
via libusb.
So what does
	sane-find-scanner
given in a console, reply? If you read something like:
	found USB scanner (vendor=0x06bd [AGFA], product=0x2061 [ 		 
Snapscan1212u_2]) at libusb:002:002
then your scanner is recognized and may be adressed by xsane or so via 
libusb.
If not, then you probably don't have sane-frontends and/or libusb, so 
get it.
The next step should be
	scanimage -L
If you DON'T read
	device `snapscan:libusb:002:002' is a AGFA SNAPSCAN 1212U_2 			flatbed 
scanner
try the same as root. If there's success at last, then there is a 
permissions issue that allows only root to access the scanner. Getting 
it to work for normal users is another story ...
As to the 'firmware' line in snapscan.conf: It's ok and should be there 
(if the .bin file really is in the indicated location)
