Thanks for your suggestions.  Changing the permissions does not make it
work for a user.  The new udev system seems to control scanner device
use.  I may try your network suggestion later, but I succeeded in
getting the scanner to work for users by adding a file
60-libsane.epkowa.rules to /etc/udev/rules.d whose contents are:

[root fc5 rules.d]# cat 60-libsane.epkowa.rules
# Epson Corp.|Perfection 4490 Photo (GT-X750)
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0119", SYMLINK+="scanner-%k"

I suspect that adding this entry to the supplied 60-libsane.rules file
would also work, but doing it this way may remind me with the future
test releases and the final release of FC6 to do this.
