the bluetooth stack "starts" the btaudio driver by enumerating the audio

cannot force enumeration of this device.

This is a basic question. Any help would be appreciated.

I've a PortCls driver (btaudio.sys) on the system and want to start
it. It appears (used DriverView utility) it is already
loaded but the sound device it represents does not appear in Control
Panel | Sound and Audio Devices | Audio & Voice
tabs.

The bluetooth stack that uses the driver seem to "start" it when I
connect to a headset for example. However, I've a situation where I
want to start this from my application.

How do I do it?

Thanks

I do use the SDK that comes with Bluetooth stack but it doesn't
provide
any functions for enumerating the btaudio.sys. If there is no way to
do it using Win32 or DDK API, can I modify msvad that comes with
the DDK to call btaudio in its lower edge?

When I load msvad, it (the "simple" device) appears on the
control panel audio devices and I was able to switch between
soundmax and simple.

thanks
