In my application that does some audio-related stuff, I constantly receive WM_DEVICECHANGE - DBT_DEVICEARRIVAL from the Vista Business OS, although there is no actual device arrivals nor removals. I think somewhere in the code or some other application could be adding some virtual devices on the ports, so I reckon that kicks off these events.
I think what I should do is to try to find a way to distinguish virtual device notifications than physical device notification.
Anyone has any idea how to achieve this?
Thanks in advance!
