Normally the Redhat package manager should take care of this unless you
compile SANE yourself. Did you upgrade from an earlier Redhat distribution? Did
you compile sane yourself at one point?
Run "scanimage --version" and compare the backend and frontend version. If
they don't match there's still a problem with your installation. In this case
I recommend to
- uninstall sane
- manually delete /usr/lib/sane, /etc/sane.d, /usr/local/etc/sane.d and
- reinstall sane

Do you have write permissions on /dev/usb/scanner0? Maybe you have to change
the access rights on the device node or add your user to a specific group to
access the scanner. Otherwise you can only access the scanner as root.

You should get an immediate error message if the scanner is disconnected. If
the scanner is warming up xsane will continue after about 15 seconds.
Everything else is a bug.
