You can try as root:
[root at fc5t3 ~]# sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make
sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04b8 [EPSON], product=0x0119 [EPSON
Scanner]) at libusb:007:002
  # Your USB scanner was (probably) detected. It may or may not be
supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary
ports
  # can't be detected by this program.

If it gives you the usb device numbers for your system as above, then

[root at fc5t3 ~]# ls -l /proc/bus/usb/007/002
-rw-rw-rw- 1 root root 50 Feb 25 09:04 /proc/bus/usb/007/002

where you replace the /007/002 with the numbers sane-find-scanner
provided.

If the permissions are not as above, then 

[root at fc5t3 ~]# chmod a+w /proc/bus/usb/007/002

for your particular device numbers.

If you are lucky, the scanner will now work.  If it doesn't, please file
a bug report.  You can see my bug report for my Epson Perfecition 4490
Photo scanner at bugzilla #182210.  My problem may be because this is a
newly supported scanner, but if you find the same thing happening, the
bug will get fixed faster if you add your input or file an additional
report.

Thanks.  Good Luck.
