For the record, iscan is not GPL.  It is GPL with an exception that
allows linking with the libesmod module.  This module is under a
license that is NOT free.  Furthermore, the epkowa backend that is
included with iscan is licensed under the same conditions as the SANE

Also for the record, for most intents and purposes the epson and
epkowa backend should be considered seperate.  There is very little
flowing back to the epson backend :-( and there have been a few
changes to the epson backend that I personally wouldn't have made.
Hence, those are not in the epkowa backend.

Seeing that you are on amd64, did you install the iscan binaries (via
`alien --install --scripts`) or did you compile from source?  You will
only get 64bit support if you compile from source.  Note however, that
in that case the iscan frontend is not built because it requires an
ix86 binary-only library.  The resulting epkowa backend should work
fine with XSane, though.

Not without more information.  Try

  SANE_DEBUG_EPKOWA=20 xsane 2> xsane-perfection-1660.log

and show me the log file.

Hope this helps,
