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.
The driver should be robust to multiple instances of the device being on the system, possibly with multiple different firmware versions. For example, there may be one instance of the device that has been connected and updated several times; a brand new device may then be plugged in which is several firmware versions old. This means that state such as current version must be stored against the device, and not in a global location.
If there is an existing method to update the firmware EXE or co-installer, for example , you can largely reuse the update code within a UMDF driver. Skip to main content. If connected via USB, skip to step 2. If connected via Ethernet, follow steps 1a - 1d to make sure the Software Update feature is enabled using the printer's Embedded Web Server. From the computer, open a web browser. Enter the printer's IP address in the Address bar and press Enter.
The Embedded Web Server home page will be displayed. If necessary, click on Log In at the top right of the page and enter the administrator user name and password. Note: Depending on when the device was manufactured or the software version installed, the default password may be the device serial number or Make sure Software Updates are enabled. If they are disabled, click on Enable and then restart the printer when prompted.
From the Printer Model drop-down menu, select your printer. NOTE: You may need to scroll to the bottom of the list. Click on Browse , then navigate to the location of the firmware update. Select the. Click Add. Click Next. The Firmware update status appears on the Update in Progress screen.
