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

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

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_USB_WORKAROUND=1 sane-find-scanner


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