Crimson,
We are in the same world.. here is what has been working for me.
I am using an M-Audio USB Mobile Pre. As far as using it in WinXP via Parallels, what I have done is installed it on the OSX side. Make sure the device is plugged in and running in OSX before launching Parralels. When I boot into WinXP, all WinXP audio is routed through the M-Audio box, (provided you OSX audio prefs are set that way) It is no different than having the WinXP audio come through the Macbook speakers.
As for software, my 2 big Windows needs are SMAART and Sports Sounds Pro. SMAART works just fine. I have input for my cal. mic.
So again, to say it another way, I have no need to attach my M-Audio box as a USB device in WinXP. Just let OSX and its System Pref's do all the work. I hope this helps
-jerm!
PS... I'm sure if your situation leave you needing multiple I/O... other than stereo... thats a whole different story... good luck with that!
