Hi Klaas,

you just got a free upgrade from a Perfection 1650 to a GT-8200...

The reason for this is that EPSON stopped shipping the scanners with
different firmware versions depending on where the scanner was sold.
In the past you could actually buy a scanner that reported itself
as a Perfection 1200, and a GT-7600 that reported this name. This
probably got too expensive, so now they just change the label
on the scanner and use the Japanese name internally. The GT-xxxx
scanners are marketed in the Asian region, the Perfections in
all other regions.

Usually you don't see this internal name (that is because most
people are using the Win or Mac drivers), but because we are
using just one backend for all EPSON scanners an not one driver
for one specific device, the GT-xxxx shows up on the user interface.

So this is just a cosmetic issue. 

The missing entry in epson.[ch] is my fault. I did report the new
IDs to David Nelson, so that they are now included in the kernel
code, but missed to update my own code. 

I can send you a patch, let me know if you need one.

Karl Heinz
