Updating the Bluetooth Stack on Your Windows XP Computer
Overriding the default Bluetooth stack in Windows XP SP2 requires some work on your part. The Widcomm Bluetooth driver is not WHQL-certified, and Windows XP uses the Microsoft Bluetooth stack by default (which is WHQL-certified). When you try to install the Widcomm driver, you will get an error message preventing you from proceeding with the installation.
To override the Microsoft Bluetooth stack, perform the following steps:
Go to Start -> Settings -> Control Panel -> System. In the Hardware tab, click on Device Manager (see Figure 2).
Figure 2. Invoking the Device Manager
Under the Bluetooth Radios item in the Device Manager dialog, you should see the Generic Bluetooth Radio and Microsoft Bluetooth Enumerator items (see Figure 3). Right-click on the Generic Bluetooth Radio item and select Update Driver.

You will be prompted to connect to Windows Update to search for software. Select "No, not this time" and click on Next (see Figure 4).

In the next dialog, select "Install from a list or specific location (Advanced)." Click on Next (see Figure 5).

In the next dialog, select "Don't search. I will choose the driver to install" and click on Next (see Figure 6).

Click on the Browse button (see Figure 8) to locate the folder containing the Bluetooth software from your manufacturer. In my case, my Bluetooth adapter is from Billionton.
Figure 8. Specifying the location of the drivers
You will notice that the model of the Bluetooth device (in my case it is "CSR USB Bluetooth Device") is now displayed in the Model list box (see Figure 9). Click on Next.
Figure 9. Installing the new drivers
The installation of the new drivers should now be started. When it is done, you should see the new Bluetooth device in the Device Manager window (see Figure 10).
