The actual firmware upgrade happens in the context of the work-item.

If firmware update is required, the UMDF driver should: Additional guidance is provided later in the document regarding placement location of firmware binary. This is done by comparing the version of the firmware on the device against the one that came in via Windows Update. During OnPrepareHardware UMDF callback, the UMDF driver shall check if the firmware on the device needs to be updated.A previously set property can be cleared using DEVPROP_TYPE_EMPTY.

The IWDFUnifiedPropertyStore interface describes how to set a property on dev-node. This is done by clearing the previously set DEVPKEY_Device_PostInstallInProgress property. After the firmware update is completed and device has reverted to MBIM mode, Windows should be notified.The entire firmware upgrade process, including reboots, should take place no more than 60 seconds.It is acceptable for the device to reboot multiple times during the firmware update process, but would cause the UMDF driver to get unloaded/reloaded.The UMDF driver shall perform the following steps to performing firmware updates It should be noted that the life time of the soft dev-node is tied to physical presence of the MBIM device. Once the IHV UMDF is loaded on the soft dev-node it is responsible for controlling the firmware update flow.WU package would contain an IHV authored UMDF driver as well as a firmware payload. It is expected that the FID represents a unique firmware SKU (uniqueness here is defined by combination device VID/PID/REV and MNO). The IHV WU package, based on the FID match, is pulled down to the machine and installed.The inbox NULL driver will used be used as default if better match driver is not available to eliminate “Driver Not Found” issue.

In Windows 8, PnP system will first attempt to install a driver from the local store, if one is available, and in parallel OS will attempt to fetch a better matched driver from WU. The creation of the dev-node will kick start PnP subsystem (Windows OS) to find the best matched driver. This referred to as “Soft Dev Node” in the diagram above.
To support firmware updates on Mobile Broadband using Windows Update, module or device manufacturers need to comply with the following requirements: The information in this topic applies to: The devices must be compliant with the USB NCM Mobile Broadband Interface Model (MBIM) V1.0 specification released by the USB-IF Device Working Group.
This topic provides guidance to Mobile Broadband (MB) module manufacturers intending to support firmware upgrade devices via Windows Update (WU).
