The scanner disappeared from the system.
It used to be present before.
I had to manually add the necessary sg device:
/etc/udev/rules.d]$ cat 20-scanner.rules 
# permissions for SCSI cd/sg devices and scanner
BUS="scsi", KERNEL="sg[0-9]*", SYSFS_type="5", NAME="%k",
GROUP="cdrom", MODE="0660"


Version-Release number of selected component (if applicable):
udev-039-10.FC3.6

How reproducible:
Always

Steps to Reproduce:
1. Install fc3
2. Start gimp, then acquire-> xsane
3. No device detected
    

Actual Results:  No devices found

Expected Results:  The scanner should be detected

Additional info:

Used to work in fc2. I fixed it by entering sg devices by hand
in /et/udev/rules:

/etc/udev/rules.d]$ cat 20-scanner.rules 
# permissions for SCSI cd/sg devices and scanner
BUS="scsi", KERNEL="sg[0-9]*", SYSFS_type="5", NAME="%k",
GROUP="cdrom", MODE="0660"
