Bluetooth Headset Hardware not supported

I have a Kensington USB dongle and I pasted the ASP info below. I can use it for pretty much everything except for using my headset. Does any one know of a way to enable this?
I can't imagine why Apple would only support headsets on their bluetooth hardware. I read in this forum that a D-link dongle is supported, does it have any specific features that my Kensington dongle does not list in the Apple system profiler?
