Hi

I've tried some vendor's VoIP phone device, I found it create self guid bus
on Windows registry, and this guid is the same as its inf file ClassGUID :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\{ guid}

So we can make our own class id device as we wish even no standard bus ,
or because it is a virtual audio driver ?

Thank for your teaching .

If it's a virtual device then you can define your own guid or string for the
bus identification part in the device-id. There is nothing wrong in it. In
fact using a guid is good approach as it avoids name collision with another
vendor.
