Hello and welcome to Tom's Hardware Forums.
No Bluetooth in Control Panel? Do you have Service Pack 2 installed? Go Start>Run and type in btcpl.cpl and hit |Enter. What happens?
Thank you for your query. When I run that command, nothing discernible happens. Momentary hour glass. I went looking in the control panel to see if the bluetooth icon would now be there but it isn't. So I connected the Plantronics again and tried the hardware wizard but still, it notes the presence of Plantronics BT, searches and can't find a driver. Device manager flags the device with yellow.
This is Windows XP Pro with service pack 3.
