sane and the samsung software for laser printer ml-2250

Hi,

the installation of the SAMsung printer software for
the printer ml-2250 (FILE:
20060711101742437_UnifiedLinuxDriver.tar.gz
from the SAMSUNG website) disables the usage of the USB
scanner CANON
LIDE 30 by non root users

I'am running fc5, and before installing this SAMSUNG printer
driver I
could scan as normal user without problem. But after
installing
0060711101742437_UnifiedLinuxDriver.tar.gz, scanning was no
more possible:

xsane

insmod: can't read
'/lib/modules/2.6.18/kernel/drivers/mfpportctrl/mfpport.ko':
No such
file or directory

Starting xsane/scanimage as root was possible on the other
hand.

After uninstalling the driver, I could again start xsane
without
problems as normal user.

The problem is Kernel independent: running the Vanilla
kernel 2.6.18 and
FC5 kernel both produce the same error results.

In the file /etc/sane.d/dll.conf
try commenting out the Samsung driver: smfp
which Samsung's Unified Linux Driver appends to this file.

I had this same problem. "scanimage -L"  worked
but "xsane" no longer did,
because xsane loads the drivers in /etc/sane.d/dll.conf and 
Samsung does not provide smtp, although it does create
device nodes
for its multi function printer.
