Sorry for not including that. The report was for "Expression 800"
entry.  The following is bug report if interested.

If epkowa.desc can include those ":scsi" that are known, it would be
great.  Since the epkowa.desc is used in sane-backend build process,
fedora would get your ":scsi" fixes when users install sane-backends
and these reports would reduce some... maybe helping isane out in the

The epson2.desc entries may need further discussion but it sounds like
my initial wish of removing a downstream patch can be addressed
sometime in near future via a epkowa.desc update.
