[Techtalk] SANE configuration files, where?

[ed orphan]

I've updated my Red Hat 7.3 SANE from the
default 1.0.1 to 1.0.8 using an rpm file from
http://www.sane-project.org
  I've looked everywhere, but I can not find
the SANE configuration files.  i have to
get the correct driver working for my Epson
Perfection 1250 ( it's the Plustek driver ).
To do that I have to find the configuration
files, but I can't find them anywhere.
   Could someone tell me in what directory
the SANE configuration files for Red Hat 7.3
are ?
