If you own a Valve Index headset, you may have noticed a USB port on the front of the device. But what is it for? In this article, we’ll explore the various uses of this USB port and how it can enhance your VR experience.

External Devices

One of the primary uses of the USB port on the Valve Index is to connect external devices. This can include things like game controllers, keyboards, or even other VR peripherals. By using the USB port, you can expand your VR setup and create a more immersive experience.

Game Controllers

Many PC games are designed to be played with a keyboard and mouse, but some games are better suited for game controllers. If you have a favorite game controller that you prefer to use, you can connect it to your Valve Index through the USB port. This will allow you to play games with your preferred input method and make your gaming experience more enjoyable.


If you’re using your Valve Index for productivity or browsing the web, connecting a keyboard can make typing much easier than using an on-screen keyboard. By connecting a keyboard through the USB port, you’ll be able to type quickly and efficiently without having to remove your headset.


Another use of the USB port on the Valve Index is for charging devices. If you have a smartphone or other device that needs charging while you’re using your VR headset, you can connect it to the USB port and charge it while still being able to use your VR setup.

Software Updates

The USB port on the Valve Index is also used for software updates. By connecting your headset to your computer via USB, you can download and install firmware updates that improve performance and add new features to your device.


In summary, the USB port on the Valve Index has a variety of uses that can enhance your VR experience. Whether you’re connecting external devices, charging your smartphone, or updating your device’s firmware, the USB port is an essential feature of the Valve Index headset.
