Update wirelessly. This controller has a small, circular 3. If you have a stereo headset adapter, plug it into the bottom of your controller so it can also get updates. If you're using a stereo headset adapter, plug in a headset a headset must be plugged in so the adapter will turn on.
Things to keep in mind. The auto-detect feature of this update may not work immediately if you plugged your stereo headset adapter into the controller while downloading a system update, or while the console was turned off. To fix this, go to the Home screen and unplug the adapter. Then, plug the adapter back into the controller. You only need to update your controller one time to use the stereo headset adapter.
Additionally, check for new updates periodically as Xbox frequently ships new controller features and improvements. Update with USB. If you have one, plug the stereo headset adapter into the bottom of your controller so it can also get updates. For original Xbox One, the port is on the left side of the console, around the corner from the disc tray. Plug the other end of the USB cable into the top of the controller.
Instructions to install the update should automatically appear. The process can take up to 3 minutes. To resolve this, go to the Home screen and unplug the adapter. The existing function driver can implement the firmware update mechanism, as shown in the following diagram:. Alternatively, if you want to update the function driver and the firmware update driver separately, create a second device node, on which you will install the firmware update driver. The following diagram shows how one device can have two separate device nodes:.
In this case, the function and firmware device nodes must have different hardware IDs in order to be targeted independently. There are a couple ways to create a second device node. Certain device types have the ability to expose a second device node on one physical device, such as USB. You can use this functionality to create a device node targetable by WU, and install a firmware update driver on it.
Many device types, however, do not allow a single physical device to enumerate more than one device node. In this case, use an extension INF that specifies the AddComponent directive to create a device node that can be targeted by Windows Update and install the firmware update driver on it.
The following snippet from an INF file shows how you can do this:. When installed, this INF creates the following device hierarchy:. To update firmware for devices that use a Microsoft-supplied driver, you need to create a second device node, as shown above. PnP resolves this location when it installs the device. The driver can then open this registry key to determine the location of the payload.
To locate another device node, the firmware driver should walk the device tree relative to itself, not by enumerating all device nodes for a match. A user may have plugged in multiple instances of the device, and the firmware driver should only update the device with which it is associated. Typically, the device node to be located is the parent or sibling of the device node on which the firmware driver is installed. For example, in the diagram above with two device nodes, the firmware update driver can look for a sibling device to find the function driver.
In the diagram immediately above, the firmware driver can look for the parent device to find the primary device with which it needs to communicate.
