PC Pitstop began in 1999 with an emphasis on computer diagnostics and maintenance. During the early days of the dot com boom, our online PC maintenance tools were skyrocketing. Using Microsoft’s Internet Explorer along with ActiveX technology, we could provide free diagnostic and maintenance tools that didn’t need to be installed. As times changed and PC Pitstop grew, we transitioned to a software subscription model to not only provide better and more secure diagnostic and maintenance tests, but turn our focus towards computer security with PC Matic.

Windows 10 has built-in USB 3.0 drivers. So you can use USB devices through USB 3.0 ports directly without installing USB 3.0 drivers manually. Due to this reason, many manufacturers hasn’t update USB 3.0 drivers for Windows 10. In this post, you will learn how to download and update Intel® USB 3.0 eXtensible Host Controller driver in Windows 10 if you have to install the driver manually. There are 2 ways introduced here you can use to download the official Intel USB 3.0 drivers. Just choose an easier way on your case. 

Way 1: Download and Install the Drivers from Manufacturers Manually
Way 2: Download and Update the Driver Automatically (Recommended)

Way 1: Download and Install the Drivers from Manufacturers Manually

When you download drivers manually, ensure that you download the drivers from official manufacturers, which are definitely safe to your computer. The official manufacturers could be your PC manufacturer (Dell, HP, Lenovo, Acer, Asus, etc.) and the device manufacturer (Intel).

It is recommended to go to your PC manufacturer’s website to check for the latest USB driver for Windows 10 first, as they may customize the driver. 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). The PC manufacturer may not release Windows 10 drivers for your PC model, in this case, go to Intel’s official website to download the driver.

If no Windows 10 Intel USB 3.0 drivers can be found from manufacturers, download the driver for Windows 7 instead, which is always compatible with Windows 10. 

The downloaded driver is always in self-installer format. If you fail to install the Windows 7 driver in Windows 10 using setup file (.exe), you may need to install the driver manually step by step using .inf file. If this is your case, follow these steps to install the Windows 7 driver.

1. Unzip the downloaded driver file to a specific location.
2. Open Device Manager.
3. Expand category Universal Serial Bus controllers and find Intel® USB 3.0 eXtensible Host Controller. Note if the driver is missing or corrupted, you will see a yellow mark next to the device. Probably, the device name will be “Unknown USB Device”.

4. Select Browse my computer for driver software.

5. Select Let me pick from list of device drivers on my computer.

5. Click Have Disk… button.

6. Click Browse… button to navigate to the folder where you saved the unzipped downloaded driver file.

7. Select the .inf file then follow the on-screen instructions to install the driver.
