USB MIDI that works on VirtualPC for OS X

[Me]

I just installed VirtualPC Win XP 6.1 on Mac OS 10.2.6 and spent
several frustrating
hours trying to get my MOTU USB MIDI Timepiece to work before MOTU
confirmed that their Win drivers do not work on VPC.

Can anybody tell me USB MIDI interfaces that they know work with
VirtualPC on OS X.

thanks much
