Hi all,

Here is a problem about Vista audio endpoint.
Suppose there are one speaker and one micropone endpoint on an USB device,
and there are two USB devices A and B of this kind plugged into Vista.
Well, how to make sure which speaker endpoint is on deivce A, and which is
on B?
Same problem could be presented on microphone, and the answer may be
different between the view of end user, and of a programmer.

thanks.
Wayne
