Unless there is yet another USB product ID I've never heard of, I
think that should be 0x4b8/0x819.  At least, that's what's in
epkowa.desc ;-)

On a related note, I recently discovered that, even if you don't need
a binary-only non-free plugin, not all epkowa supported devices work
with the epson backend.  In my case, this happened with a PM-A750 (aka
Stylus Photo RX520/530).  I haven't really looked into it but if first
impressions are anything to go by it may have to do something with the
(not) sending of the ESC i command and the processing of its reply.

# Me goes back to work ...

Hope this helps,
