Program: Band-in-a-Box 2011, Real Band 2011
OS: Windows 7 SP1
ASIO Driver: M-Audio USB 2.0 ASIO
Audio Interface: M-Audio Fast Ultra 8R
Results: No problems whatsoever. As usual cannot use ASIO in two programs at same time - but then I run BIAB with MME and all works.

BTW - I think Processor speed and power has a lot to do with the latencies achieved - more power, lower latency.
