Oops ! I was using XSane and I compared a *grayscale* scan made by the 
epson backend and a *black and white* scan made by the epkowa backend. 
The grayscale one was better. Sorry for that.

My scanner wasn't recognized until I had a line in libsane.rules. And I 
read this at the top of this file:

  # The following list already contains a lot of scanners. If your scanner
  # isn't mentioned there, add it as explained above and mail the entry to
  # the sane-devel mailing list (sane-devel at lists.alioth.debian.org).

I wrote this mail to get my scanner id added to libsane.rules. Maybe I should 
have written to Ubuntu instead ?
