Hi Tony, this is the dongle that you can select as an add-on during twiddler purchase. It says LM506 on it.
My expectation is that it would work like the bluetooth dongle for my headset. I plug it in, and the headset pairs with the dongle right away, even if bluetooth is turned off on the macbook. This allows me to use the headset via USB instead of the less reliable bluetooth connection.
Does the twiddler dongle not work this way?
The dongle doesn't appear as something other devices can pair to.
