Hi, Gerd.  First of all, make sure your parallel port is set to either
"bidirectional" or "ECP" in your BIOS setup.  Alternatively, you could try
using the "usenibble=1" switch when insmoding ieee12844pp.o.

If none of those suggestions work, then it would be helpful if you tried
turning on debug output for the kernel drivers, at least ieee12844pp.o.
This is documented in the INSTALL file.  If you'll e-mail me the relevant
debug output in /var/log/messages, I'll take a look at it and see if I can
find anything suspicious.

If you don't mind living on the "bleeding edge", you could also try the
development code in CVS, which has completely different low-level drivers
and may provide a better clue about what's going on.
