See man sane-gt68xx. Vor an overview about sane and all the sane
manual pages, see man sane. Or do you mean that the sane-gt68xx manual
page is not in the debian package? In this case, file a bug report in
the Debian bug tracking system.

Not strictly necessary for this scanner but it won't hurt.

That's mostly the same scanner driver.

At least the firmware of my 2400 CU Plus is named "PS2Dfw.usb".
"PS2fw.usb" is the firmware for the 2400 CU (without plus), a
completely different scanner.

Put it after the "usb 0x055f 0x021d" line.

/dev/usbscanner0 is only used by older distributions. Newer ones
usually use /dev/usb/scanner0. But it doesn't really matter.

If you use kernel 2.4.21.pre4, you won't need the options.

Ok, so from the kernel point of view your scanner was detected
successfully.

Have a look ath the debug output:
SANE_DEBUG_GT68XX=255 scanimage -L

If you can't find out what's wrong, send the debug output to this list.
If you don't get any debug output, check that "gt68xx" is in dll.conf.

Bye,
