Dead as far as I'm concerned
Look, the USB port is going to supply 5V to anything plugged in. That means the adapter is going to energize and start transmitting. Any other bluetooth device in the area is going to be able to sense the adapter....
But the Mobilepro is not sending any useful data to the usb bluetooth adapter...so until someone comes up with some specific drivers that direct i/o to that port...it is useless.
