If you have installed Bluetooth dongle driver from the manufacturer or third party drivers it is necessary for you to install the standard drivers from Microsoft.
To do that, follow these simple steps:
- Uninstall all third party Bluetooth drivers then reboot your PC.
- Let Windows detects your Bluetooth hardware. Wait until Windows detects new hardware and installs its drivers. If Windows found new device and installed it correctly then done. Otherwise follow to the next step.
If Windows did not install drivers for your Bluetooth device we must teach it how to do it:
- Open your file manager and change it settings for showing system and hidden files.
- Go to Windows folder (for example C:\Windows) and find there folder Inf. If you can't find that folder check that Show hidden files option checked in Windows Explorer settings.
- Open it and find here bth.inf file. If you can't find that file then you have unchecked Show hidden files option or does not have Windows XP.
- Go to Device Manager and find there Unrecognized device.
- Open its property sheet go to Detail tab and remember text which looks like this: USB\VID_1311&PID_0021\B7E4090D0B00.
- Next, find in bth.inf file this text line: USB Bluetooth Wireless Adapter = BthUsb, USB\Vid_1310&Pid_0001.
- Now you must change Vid_1310 to the Vid_1311 (like in remembered text) and Pid_0001 to the PID_0021.
- If you have other remembered VID and PID then you must change it to your.
- Save changes in bth.inf file and reboot your PC.
- If the Bluetooth device not found go to the Device Manager and refresh devices list.
