How to use a bluetooth dongle instead of built-in BT?

Question

Just got an "Ultra Long Range Industrial" bluetooth dongle (BTD Bluetooth Dongle BT-6610).  I want to use it instead of the built-in bluetooth because it has a much longer range.
How do I disable the built in bluetooth and enable the BT-6610?
The dongle shows up:

Answer 1

Hi X42:
Your last paragraph intrigued me as I had the same impression:
  I thought unlicensed BT devices were legally limited by the FCC to about 30 feet (3 meters)
Actually, 30 feet is 10 meters. 
Anyway, I researched and found this as part of a Wikipedia item:
Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range (power-class-dependent, but effective ranges vary in practice; see table below) based on low-cost transceiver microchips in each device.[7] Because the devices use a radio (broadcast) communications system, they do not have to be in visual line of sight of each other, however a quasi optical wireless path must be viable.[2]
Class
Maximum Permitted Power
Range
(approximate)
mW
dBm
Class 1
100
20
~100 meters
Class 2
2.5
4
~10 meters
Class 3
1
0
~5 meter
The effective range varies due to propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices.[8]
Apparently there are BT devices that will transmit about 300 feet.  I did look at the FCC site, but quickly became confused in the technbabble.
