The User Agent MAY fire just a single event when several devices are added at the same time, e.g. a camera with a microphone.

There are some limitation on OSX to support this.
When I plug in my Logitec webcam, AVfoundation only fire two plugin events without more detail.
It doesn't indicate the two events are from the same hardware or not.
It means I can't distinguish the case user plug in a webcam with cam & mic from the case user plug in 2 USB cameras in the same time.
Currently the only solution comes to my mind is to use a timer, to filter out the 2nd events which arrives after the 1st one within X ms. But there will be some overkill. It is also a problem about the magic number we set to X.
