I installed ver 10 beta without a hitch but I'm a bit clueless & lost as to why SANE says it'll support my SCSI Umax scanner & the OS finds it but it no worky.
It's my first post here, & I've never run a scanner under Linux, so please be gentle.

found SCSI scanner "UMAX UMAX S-12 V2.1" at /dev/sg3
# Your SCSI scanner was detected. It may or may not be supported by SANE. Try
# scanimage -L and read the backend's manpage.
# No USB scanners found. If you expected something different, make sure that
# you have loaded a kernel driver for your USB host controller and have setup
# the USB system correctly. See man sane-usb for details.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
[root@localhost ~]# scanimage -L
