Ouch ;-)

Looks fine to me.  The only thing I think a little odd is all those 
epson backends lying around.
Note that older versions of the iscan package would silently clobber 
libsane-epson.so.1.0.6 and the symlinks to it.  You may want to play 
safe and make sure that libsane-epson.so.1.0.6 is the sane-backends'
version.

Plenty!

You also don't get the dreaded "Could not send command to scanner" error 
message box from iscan?  Hmm, ...  What output does

  SANE_DEBUG_EPKOWA=256 iscan

generate?  Perhaps that gives a clue.

It should not matter where you build.  I built our binaries in two Red 
Hat chroot jails (one for 7.3, the other for 8.0) on my Debian machine 
where I work on iscan compiled from somewhere below $HOME (and it gets
installed someplace very different from where the Debain sane-backends 
are installed to boot).  Everything works fine, even the Perfection 1250 
and 1260.

Vendor and product ID are fine.

I'm running out of ideas :-{
