Sorry for not getting back earlier.  "Real Work" got in the way.

That's OK.  The lists of horizontal and vertical resolutions are not
the same and the latter has more entries.

Apparently, something went wrong when initiating the scan but from the
log I can't really tell what.  Please try previewing in colour with
scanimage as follows:

  SANE_DEBUG_EPKOWA=127 SANE_DEBUG_SANEI_USB=127 scanimage --mode Color --resolution=200 --preview=yes > image.pnm 2> debug.log

(all in one command).  This may create a boat-load of debug info so
please compress it and send it *off-list*.

Hope this helps,
