USB Bluetooth Dongle

Here is the situation:

I want to use a Mac Mini as a media center computer and hook it up to my television via HDMI... I have found the DisplayPort -> HDMI adapter and that is all good. Here is the issue.

All my components etc are down in my basement and I use an IR repeater to get remotes to work.

I would like to put the mac mini down in the basement with the other components and am looking for a USB Bluetooth Dongle that I can run a usb extension from the mac mini up to my TV area, then have my bluetooth mouse and keyboard on my coffee table and be able to run the mac mini.

I have found several mac bluetooth Dongle's on Amazon, but when I read the notes they say that they are actually NOT compatible with the Mac...

So here is my question: Has anyone found a mac compatible Bluetooth Dongle that they KNOW works?

thanks for your time!

Look for a D Link DBT-120 USB2 Bluetooth Adapter and is Mac compatible with OS X.4.3 and higher.
