To summarize the problem: I've been stuck for several weeks with a Xen
problem at a client site. I have a domU guest that needs access to a
parallel port for an old license dongle. I've tried both an on-board
parallel port, and currently a PCI card without success.
Currently, as a diagnostic move to make sure this isn't a guest OS problem,
I'm booting up Knoppix as the guest. I've also replaced the dongle with an
HP Laserjet 4 printer, so we can ignore any dongle-specific issues.
The original OS (Win2K) seems to know the PCI parallel port is there, but
can't talk to it (ParVDM error 2 - unable to get device object pointer for
port object). I tried the normal fixes for that error without success.
Knoppix 5.1.1 can't see the device at all (nothing from lspci or
/proc/ioports, either with or without pci=routeirq).
Below are the relevant files and info. I'm really stuck on this, and could
use some help figuring it out. I think I'm close, but I've missed a step
somewhere.
