For my customers and products, it is this difference that drives our need for USB Audio Class 2.0 support: 'Complete support for high speed operation - no longer are audio class devices limited to full speed operation.' What I would like to eliminate is the on going engineering efforts that we must expend to keep our USB Audio Class 2.0 driver updated and supporting multiple Windows versions. It would be so much better if Microsoft did what nearly every other platform does and natively support UAC2.

It was about interest in a class driver. It's great seeing the lively discussion. Regards, Frank Yerrace Microsoft Corporation Sent from Windows Mail
