It should work like this and the printer does.

Ubuntu already installed Sane 1.0.14-1.

I tried different things I found, like:
http://www.elijahlofgren.com/ubuntu/#scx-4521f
with no success.

Trying to start xsane from shell shows the following message:
insmod: can't read
'/lib/modules/2.6.17-10-generic/kernel/drivers/mfpportctrl/mfpport.ko':
No such file or directory
Segmentation fault (core dumped)


When I start the Samsung Unified Driver Configurator (which installs
itself) and then click the scanner button, it closes, with the messages
below.

~$ /opt/Samsung/mfp/bin/Configurator
insmod: can't read
'/lib/modules/2.6.17-10-generic/kernel/drivers/mfpportctrl/mfpport.ko':

But I don't know, whether I need mfpport.ko or where I get it from.

Samsung told me, the driver was not testet with Ubuntu.
