How to update to the latest driver

Option 1 – Manually

You’ll need some computer skills and patience to update your drivers this way because you need to find exactly the right driver online, download it and install it step by step.

Option 2 – Automatically (Recommended)

This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Method 1: Manually

Before you get started, ensure that you know the PC model and the specific operating system that you are using (Windows 10 64-bit or Windows 10 32-bit).

When you download drivers manually, ensure that you download the drivers from ASUS official , which are definitely safe for your computer.

2. Select your operating system.
   
3. The latest version of the Asus USB-BT400 driver will show up.

4. Click theDOWNLOAD button.
5. Unzip the downloaded driver file to a specific location.
6. Once complete, go to the Win10_USB-BT400_x86-x64_Installer folder, and locate the setup application.
7. Right-click setup, and selectRun as administrator .
   
8. The downloaded driver is always in self-installer format, so you’ll just need to follow the on-screen instructions to complete the installation.

If unfortunately, you fail to install the Asus USB-BT400 driver this way, you can try a much easier method — update it automatically with Driver Easy .
