George, thanks for all the additional input.  However, after looking at
the logs, none of it appears to be relevant (at this point), so I'll
snip that in the interest of brevity.

Yes, my bad, I ment "2> scan.log" and did not expect a very different
log if the interpreter didn't load.  The help.log indicates that the
interpreter doesn't load, as I expected.  You have a

  usb 0x04b8 0x013a

in your /etc/sane.d/epkowa.conf that should *not* be there.  I have no
idea how it got in there, unless you did so manually.  Take it out and
check whether that makes things work.  If not, read on.

The post installation scripts that come with the iscan related packages
normally set things up to work out of the box.  Seeing that you are on
Gentoo, that may not have worked for you.  You can fix that up with

  sudo iscan-registry --add interpreter usb 0x04b8 0x013a \
    /usr/lib/iscan/libesintA1 /usr/share/iscan/esfwA1.bin

assuming everything is in the normal locations.  This should modify
/var/lib/iscan/interpreter which is parsed by the epkowa backend.

Hmm, I now see from your log that the epkowa backend is looking in
/var/lib/lib/iscan for that file.  That's may be due to a slightly
different ./configure time variable.  See if you have something in
/var/lib/iscan and move it to /var/lib/lib/iscan (or make the latter
a symlink to the former).  That might also fix things.

If you really don't want to mess with these files below /var/, just put

  interpreter usb 0x04b8 0x013a /usr/lib/iscan/libesintA1 /usr/share/iscan/esfwA1.bin

to your /etc/sane.d/epkowa.conf.  The stuff below /var/ is just an
"easy" way for the package management system to make interpreters
(un)available as they are (un)installed.

Hope this helps,
