The 1650 and the 1250 are qutie different!!!!

Here's the problem!!! The 2.4.2 does not support the automatic detection
of scanners by a backend... see below!

Okay so far!

NO NEED TO DO THIS FOR USB DEVICES!!!! This driver is only good
for the Plustek parallel port scanner.

For Kernel 2.4.2, this one is correct!

As said before, the Plustek module is not needed, only the Plustek-backend,
as this controls LM983x based scanners. The LM983x is an ASIC, developed
by National Semiconductors, to build cheap scanners. And such a beast is
inside the 1250.

Well, the main problem currently is the calibration. But do a test on your
own before bringing it back...
You only have to alter the plustek.conf file in your sane.d directory to
enable the EPSON, the following entry should be enough to enable it:
[usb] 0x04B8 0x010F
device /dev/usbscanner
Hope this helps
