[OpenIndiana-discuss] Virtualbox and USB webcam

[Till Wegmueller]

Hey Tony

Here in the EU I always get myself a USB Gaming Headset for my Audio 
needs. They are Cheap(ish) and you can get yourself a Wireless Headset 
that has a dedicated receiver that needs no special driver, other than 
Audio. You might also get away by simply using the Mic, Headset on the 
host and using Virtuablox Audio.

And thanks for that Note that may be why I was unsuccessful in the past 
with certain pass through combinations.
