you need an XP driver. You might be able to use an NT or 2000 driver. I've gotten everything to work in XP with NT drivers by changing it to a STANDARD PC from ACPI.
If it is a software problem, you might not have the PORTS setup. I don't know the software you are using so just do a Midi Port help search.
