There is a kernel/sane bug which breaks many USB scanners. Make sure
you have at least version 1.0.25 of SANE installed.
I installed sane-backends version 1.0.27 from Sauerland OBS repository,
but the scanner still isn't recognized in yast Scanner configuration
window.

Driver Scanner
epkowa Epson (unknown model) at epkowah:usb001:004
Not Configured EPSON Scanner USB scanner (vendor=0x04b8 [EPSON],
product=0x0130
[EPSON Scanner]) at libusb:001:004

From http://www.sane-project.org/
The Linux USB3 workaround which was added in version 1.0.25 is now
disabled by default. If you have difficulty using a scanner which
previously worked, or intermittent scanner availability, try setting
the new environment variable SANE_USB_WORKAROUND=1 before starting
your frontend.
I don't know where to do this, I will need more detailed instructions.
Use sane-find-scanner and "scan-image -L" on the command line to see
whether SANE can see the scanner.

Here are the readouts:

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=0x0130 [EPSON
Scanner]) at libusb:001:004
  # 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.

scanimage -L
device `epkowa:usb:001:004' is a Epson (unknown model) flatbed scanner
