You didn't tell what version of sane-backends you use.

In OpenSUSE 13.2 we provide the sane-backends 1.0.24 release
but perhaps you might need a newer sane-backends development
version.

I provide sane-backends version git20150804 RPMs an unstable
development source only for testing, without any guarantee or
warranty, and without any support in my openSUSE build service
home project "home:jsmeix".

Please carefully read
https://build.opensuse.org/project/show?project=home:jsmeix

You can get the packages in the "home:jsmeix" project
for example for openSUSE 13.2 via this direct URL
http://download.opensuse.org/repositories/home:/jsmeix/openSUSE_13.2/

When you like to upgrade an installed sane-backends 1.0.24 release
to sane-backends development version git20150804 you need to install
version git20150804 with plain rpm using "--force" e.g. like
# rpm -Uhv --force sane-backends-git20150804-3.1.x86_64.rpm
because for rpm the version number git20150804 is lower than
the installed version number 1.0.24.


Only if your scanner is connected to a USB3 port at the computer:

There are currently issues with USB3 ports at the computer.

Basically the xhci kernel module that is used as driver for
USB3 ports has issues. It seems at least kernel 4.1.1-040101
is needed to have this particular issues fixed in the kernel.

There are some workarounds in newer sane-backends development
versions to deal with the USB3 xhci kernel module issues
in older kernels.


Kind Regards
