If you have the plugin installed, it ought to work with other SANE
frontends as well.  But wait!  You run on AMD64, right?  It won't work
with 64bit.  You will need to run all your SANE stuff in 32bit mode.

Up until iscan-1.17.0, the source and binary packages included all
plugins.  The list of plugins kept growing, leading to ever larger
source tarballs and binary packages.  So with iscan-1.18.0 we split
the binary package into a core package and several plugin packages.
With iscan-2.0.0 we also dropped the plugins from the source tarball.

This leads to a situation where now you just install the core package
and have out-of-the-box support for the majority of EPSON devices.
Only a select few require a single plugin to get the same kind of
support.  You only install what you really need now and are no longer
"burdened" with a load of non-free binary stuff you don't need anyway.

FTR, the binary packages went down from close to a megabyte to about
one third of that and the source tarballs from about two megabyte to
half that.

The upcoming release will have (experimental) udev support as well,
making things even easier.

Hmm, that's weird.  If listed in the window to choose a device, the
backend did see the device allright.  Could you take a look at the
debugging output?

  $ SANE_DEBUG_EPKOWA=50 iscan 2> debug.log

The output will end up in the debug.log file.
