Hi Gerhard,
thanks for your help and patience.
It's working now. :-)

There is still one question.
During the installation I made at least "make load", normally the driver and
device must automatically load, but it was not on this way.
Now I made it with the command
"mknod /dev/pt_drv c 40 0 -m 664"
and now it's looking as if the driver, modul and device is load if I start
"XSane"
Can you explain me why it is now going on, also if I shut down the pc and
later after the boot I start XSane it is working, without a new command?
Perhaps you will say that's a silly question, but I can't find any explanation
for this.

I have checked it, look the output
--------------
depmod: *** Unresolved symbols in /lib/modules/misc/pt_drv.o
depmod: get_fast_time
/lib/modules/misc/pt_drv.o
nathan:/home/karsten #

What does it mean?
Again.
Thanks for your help!
