Hi John,
this topic has been talked about before at i.e. Technote forum. It was a problem using Techdriver in WindowsXP.
If I don't remember it wrong, the solution until Technics releases a updated driver is to try Yamaha's or Roland's drivers.
I think the conclusion was that it works very well.

Roland driver is to be found here:
