Use the driver update routine. The Device Manager can be opened by right clicking on the âMy Computerâ icon and selecting the âPropertiesâ menu option. When the Properties dialog appears select the âHardwareâ tab and then click the âDevice Managerâ button.
When Microsoft stack is in control then the Bluetooth Radios category is present in the Device Manager as shown below, Figure 1. There will be 2/3 devices under that category, depending
on the implementation, these are:
* Bluetooth Printing Support
* Microsoft Bluetooth Enumerator
* The âActual deviceâ.
Highlight the âActual Deviceâ. Select âAction -> Propertiesâ menu option. Select Driver tab. Verify that the provider is Microsoft. Click the âUpdate Driverâ button.
When the Hardware Update Wizard appears, we are now ready to install the WIDCOMM Bluetooth driver. Select âInstall from a list or specific location (Advanced)â radio button and click on the âNextâ button to continue.
In the following screen select "Don't search. I will choose the driver to install" checkbox and click on the âNextâ button to continue.
The next dialog provides the selection between Microsoft and Widcomm provided drivers. Select the last device (USB Bluetooth Radio) in the list and click on âNextâ button to continue.
