[ How-to ] BTD-400 Driver Installation

Windows 10 may report that the driver is not available for the BTD-400.  In that case, installing drivers is necessary in order to use the BTD-400.

Let’s first check the status of the drivers:

  1. Hold down the WIN key, then press the R (Win+R) key.  Type “Control” then hit enter.


  2. Select Hardware and Sound


  3. Select Device Manager


  4. The Bluetooth driver should be located under Other Devices


  5. Right-click BCM20702A0 and select “Properties”.  You should see the following error.  This confirms that you have the Windows 10 October 2020 update.


Installing the Missing Drivers

You may be able to install the drivers via Windows Update.  Hold down the WIN (Windows Logo) key, then press the S key.  Type in update and select Check for Updates

Click on Check for Updates..

Click on View all optional updates.

Expand Driver updates.

Scroll down and select Broadcom Corporation, then click on Download and install.  It should take no more than 5 minutes to complete the installation.

Check the Device manager to confirm that the drivers installed.  The device should be ready for pairing.

Kudos to the person(s) responsible for writing the instructions for troubleshooting missing driver/update. I am 75 years old and what a pleasant experience I had following your so-easy-to-follow instructions and getting Bluetooth back.
I am a happy “camper” once again.

Hi, Tom! Welcome to the forums, and thank you for the feedback. He put a lot of work into it, and he’ll be glad to hear it’s been helpful.

That driver does not show up under windows update for me. Why doesn’t Kinivo provide the driver as a download on the support page anywhere?

Well that still doesn’t work following subsequent WIN 10 updates…waste of money.

Have you found a solution yet I am having the same issue with the windows update option not working…

Same issue with installing BTD400 Bluetooth device on a windows 10 PC.

BTD-400 out of the package, Windows 10 doesn’t find it, followed the above instructions and it’s working.
Bought this to replace old Kensington 33348, which couldn’t find my xbox controller. BTD-400 found it straight away.

Wow, this is still a live issue in 2022. What in the world are they doing over there at Redmond? The workaround in the OP worked for me.

I am trying to install the BTD-400 driver with Windows 10. I follow all your instructions. Computer recognizes device, but when I go to Optional Updates, Broadcom Corporation is not listed. Any suggestions?
Thank you,
