That might be a bit problematic as the :interface keyword seems to
take an implicit list of interfaces.  From doc/descriptions.txt

  `:interface' defines how the device is connected to the
  computer. Its string argument can be one or more of "SCSI", "USB",
  "Parport", "Serial port", "IEEE-1394", "JetDirect", "Ethernet", or
  "Proprietary".

At least the epson.desc, epson2.desc and epkowa.desc have entries with
multiple interfaces defined.  Something like

  :interface "SCSI USB"

Correct.

Hope this helps,
