Sorry I had thought the list we had was complete, and that it was a new model
being talked about.

>From the Install file I can see that the full list of supported models is:-
Epson Prefection
1240
1640
1650
1660
2400
3200
4870
4990 (not ICE)
&
GT-7000
GT-9800

& the GT15000 with a modified TWAIN we can supply

I wonder what the USBDevs file in Resources is for?
