Hi Nugen

I'd qualify this by checking your latency requirements. If you need latencies 
of less than 20ms or so then it going to be very hard to do with the existing 
USB stack. 

It is also wrth mentioning that the KS interface is likely to be dropped in 
Vista so the investment in time may be of limited value. Some of the Microsoft 
people here may be able to comment on this.

A quick way to test latency and stability is to try ASIO4ALL 
(www.asio4all.com). This is an ASIO interface to KS. You can then use an ASIO 
compliant application like Cubase to test your hardware (or write something 
using PortAudio or similiar)

Off the shelf USB drivers can be had here:

that these will offer considerably better performance.
