Bluetooth driver for XP - how to re-install

I have a microsoft wireless transceiver for bluetooth 2.o that controls my

mouse and keyboard. It plugs into my USB port.

I can only assume the ms XP driver has been corupted. I have removed and

loaded the software several times, but it will not install the wireless radio

for bluetooth.

Everything I have read says that it is included in the xp sp2. I have sp3,

so it will not re-install the sp2 pack, which includes this driver.

Any clue as to how and where to get this driver for re-installation?

I have tried a new transciever 3rd party, but it does not install the

microsoft ones I need for my original ms transceiver, and it "goes to sleep"

every 10 minutes and takes a minute for my keyboard/mouse to come active

again.

Very frustrating.
