    If you have a other free USB port it is simple:
USB PORT 1: install your bluetooth dongle manufacturer's driver or windows's default driver.
USB PORT 2: install MotioninJoy Bluetooth driver.
Select one port to plug the bluetooth dongle . by this way you can switch your bluetooth driver for different application.
     If you only one USB port for your bluetooth dongle:
Go in to windows device manager swith the driver. this way is little complexer than the other one.
