Windows 7: Bluetooth dongle and A2DP

I need some advice. I just built a new computer based on an Asus M2A79XTD mobo, AMD Phenom II X4 955, running Windows 7 X64. I installed a cheap Ultra BT dongle (I was in a hurry and it was all the store had). Long story, short; I've spent two days screwing with Bluesoleil BT software and drivers (that came with the dongle) which crashed my system. I eventually deleted everything and the dongle is now using the generic Windows 7 drivers. My BT Logitech MX5000 keyboard and mouse are working again. However, I still cannot get my Rocketfish stereo headphones to function, which was the whole purpose of replacing the old Dell BT transmitter that I had.

The headphones need A2DP. I've ordered a Targus dongle which is advertised as being compatible with Windows 7 and supports A2DP. The software that comes with it is Broadcomm not the Chinese Bluesoleil. The instructions state that the software should be loaded before the dongle is installed.



Can I just pull the old dongle, install the new software and then plug in the Targus dongle, or do I need to remove the old BT drivers from system manager and reboot before installing the new BT software. I'd like to make this a efficient as possible. I have spent more time trying to get a BT connection with my headphones that it took to build the entire computer from scratch and reload all my programs. Very frustrating. I'm about ready to go back to wires.

Any help would be appreciated.
