@JSM, you were lucky and I'm glad that you were.
But don't do this:
I KNOW how to set up both software and hardware to have maximum performance. And this WAS NOT relate to performance.
The M-Audio Fast Crap Pro unit has a problem with decoupling it's USB data lines from laptop. When it's audio I/O receives DC offset, it affects the data lines and interrupts the packet flow which in turn is reproduced as disconnected unit or loud audible noise.
I have done extensive research on how to remedy this problem and had some luck with this circuit:
Attachment 6695
Some unit owners haven't been this lucky tho. For example, guy named Al Taylor sent me a document (that I'm linking here), which goes into detail how to actually solve this problem.
