I found that the Compusa SKU.312330 USB Bluetooth
adapter with external antenna works with headphones
in addition to the DLink. When you run the firmware
upgrade on the CompUSA adapter it says that the
Firmware is up to date. So it works out of the box.
Now to clarify, both adapters do set up headphones,
but as soon as I select the headphones in the Sound
Output Preferences I get the "Bluetooth Audio
Failed..." message and they don't work. This happens
with the CompUSA and the DLink adapter and with both
a Jabra BT110 headset and MacAlly BlueWave
headphones. I am running OS 10.4.5.
