One may randomly encounter a Windows Vista/7/8 installation where some bluetooth devices don’t get their drivers installed despite having installed all of the manufacturer’s drivers.
In such cases, you’ll end up with one or several non-functional “Bluetooth Peripheral Device“.
To solve this, start by downloading and installing Windows Mobile Device Center 6.1 (local copy here). The name says it’s only for Vista 32bit, but it will also work on 7 (both 32 and 64bit).
Then attempt to update driver on the non-functioning item in Device Manager.
Select the automatic search for a driver | In the next step, select to pick from a list of drivers | In the list, look for “Bluetooth Radios” category |
Next, locate and select “Microsoft Corporation” in the left list and select the only available item in the right list. | Ignore the warning and click Yes to continue | Installation is complete. |
Repeat the above steps for each non-functional Bluetooth Peripheral Device. In the end, you should end up with several “Windows Mobile-based device support” items in Device Manager.
