This topic describes how to update a removable or in-chassis device's firmware using the Windows Update (WU) service. For information about updating system firmware, see Windows UEFI firmware update platform.
To do this, you'll provide an update mechanism, implemented as a device driver, that includes the firmware payload. If your device uses a vendor-supplied driver, you have the option of adding the firmware update logic and payload to your existing function driver, or providing a separate firmware update driver package. If your device uses a Microsoft-supplied driver, you must provide a separate firmware update driver package. In both cases, the firmware update driver package must be universal. For more info about universal drivers, see Getting Started with Universal Windows drivers. The driver binary can use KMDF, UMDF 2 or the Windows Driver Model.
Because WU cannot execute software, the firmware update driver must hand the firmware to Plug and Play (PnP) for installation.

Typically, the firmware update driver is a lightweight device driver that does the following:

Submit your firmware update package as a separate driver submission.
Adding firmware update logic to a vendor-supplied driver
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:

ComponentIDs = ComponentDeviceId indicates that the child device will have a hardware ID of SWCComponentDeviceId . When installed, this INF creates the following device hierarchy:
For future firmware updates, update the INF and binary file containing the firmware payload.
Adding firmware update logic to a Microsoft-supplied driver
To update firmware for devices that use a Microsoft-supplied driver, you need to create a second device node, as shown above.
