Right, ASIO isn't Windows its 3rd-party to work around the Win7 issues.
WaveRT is what WDM uses, right? With the associated delays going user/kernel mode. How does that help?
And USB devices are polled, at three levels as I recall - 'control', 'interrupt' including 'isochronous' and 'bulk transfer'. The frame interval depends on the USB speed - and I see they are sub-millisecond. SO very adequate for audio sampling. I used to use it for serial protocols, and that frame rate was entirely inadequate for signalling so I formed my low opinion of USB at that time.
