Ok, so just for the record: 26 of my 29 scanners work fine with SANE :-)

Same kernel version?

The source code does not depend on any specific glibc version. In
fact, it doesn't depend on glibc at all.

The source code from mostang.com works. Believe me :-)
Ig you give more details, we may find the problem. But as you say the
scanner orks eith the "Old" sane-backends package, it should also do
on the other computer.

Ignore all this high-level stuff unless you really know what it means.
Does "KDE say's it's just fine" mean that he kernel scanner driver has
detected the scanner and the permissions are set up correctly? I'm
pretty sure KDE just doesn't know. So ignore it.

Start with the basic tests and then go to the more complicated ones:
Is the scanner found by sane-find-scanner? If it's not found, even not
as root, it wasn't detected by the kernel scanner driver. You may need
to use modprobe options to get it detected: something like "modprobe
scanner vendor=0x1234 product=0x2345". Get the correct ids from syslog
or one of the USB tools you mentioned.
If it's detected, run scanimage -L. Not found? Check that "plustek" is
in dll.conf and /dev/usb(scanner0 is mentioned in plustek.conf
(instead of the default /dev/usbscanner). If it still doesn't work, run
SANE_DEBUG_PLUSTEK=255 scanimage -L
And show us the output.
I'll rewrite the PROBLEMS section of the sane manpage now so I can
xopy this explanation the next time :-)
