Bluetooth Dongle No Longer Working

Anonymous

Hi, 

I have a Asus Bt400 Bluetooth adapter that was working with my PC Windows 10 Pro. Usually when I'm not using it I unplug it. When I plugged it in to back up my phone and tablet Windows recognises it but I cannot use the device. The drivers are the latest and the only changes recently have been windows updates. When I run the trouble shooter it says I need to plug it into a USB 2 socket. Now I have various USB 3 and 2's on my PC and I always plug it into the same USB 2 when using Bluetooth. On this occasion I plugged it into other USB 2 sockets and Windows insists it is plugged into a USB 3 when it is not. 

Any help would be appreciated. 

Regards 

David.

    What is the make and model of your computer?

    Which version of Windows 10 is installed?

    Go into BlueTooth Settings > Devices > Bluetooth and other devices > then unpair/remove the device, restart then pair it again.

    Use the Add Bluetooth wizard in Control Panel

    Press Windows key + R

    Type: control printers

    Hit Enter

    Click Add device then add the Bluetooth device again.

    Have you checked for updated chipset drivers for your make and model?

    Also, some manufacturers will provide separate Bluetooth drivers.

    Press Windows key + R

    Type: services.msc

    Hit Enter

    Scroll down to Bluetooth Support Service

    Right click it

    Click Properties

    Under the General tab

    Click in the Startup type: listbox

    Choose Automatic

    Click Start

    Click Apply then OK

    Restart your computer then check if its working.

    Other things you can try include the Bluetooth troubleshooter.

    Open Start > Settings > Update & security > Troubleshoot

    Scroll down to Bluetooth

    Click Bluetooth then click Run the troubleshooter

    When complete, Restart your computer.

    Press Windows key + X

    Click Device Manager

    Expand Bluetooth

    Right click each entry then click Properties

    Select the driver tab, click Rollback if its not grayed out.

    If it is grayed out, right click Bluetooth driver then click uninstall

    Restart your computer then check if its working again.

    If not, remove any other Bluetooth devices since they might be causing interference .

    You can also try pairing through Devices and Printers. Learn more:

    Hello, David! Are you having any trouble with any other USB devices? Can you use the Bluetooth dongle in a different PC and see if it functions?

    Thanks for the help guys, Bluetooth is now working. We'll I say working I cannot pair to my phone or tablet as Windows tells me it fails and the devices say the passcode/pin failed. Windows did not give me any pass code and the pass codes received on my devices can't be authorised due to Windows failing prior to me accepting on the devices.
