Vendor supplied firmware update driver will load against this device and updates the firmware. The device enumerates as a firmware update device.

A vendor supplied lower filter driver that performs the firmware update.Ī vendor supplied lower filter driver that puts the device in 'firmware update mode'.

There are two ways the firmware could be updated: The installed driver package will perform the firmware update. After the installation of the generic driver, the OS queries the Windows Update server for any vendor specific driver package availability and downloads it and installs the driver.

When a USB device is plugged in to the system, the generic inbox driver is installed for the device. During the AddDevice call, the filter driver will check the device firmware version and update the firmware if necessary. The recommended method to circumvent the absence of a co-installer for the USB device firmware update scenario is to use a lower filter driver to the USB device that will kick start the firmware update process.

The absence of co-installers on Windows 10 prevents device vendors from updating the firmware on these devices in the field. The co-installer kick starts the firmware update process.

Typically, as part of the device installation process, the firmware updating software suite is installed. One item that is common to all existing update mechanisms is that some custom software suite runs on the client and downloads the firmware to the device. There is no standard method to update the firmware today. USB devices like UVC cameras are released with in-field updatable firmware.

Reliable recovery mechanism (for example, no bricking of devices) Seamless firmware update with no user interaction The primary requirements from the USB device firmware update process are: This topic outlines a recommended method to update USB device firmware without a co-installer. This poses a challenge to existing USB device firmware update process. However, co-installers are not supported by the new 'Universal INF' standard, which is a requirement on Windows 10. USB Device vendors use co-installers to update device firmware for devices that use inbox USB device drivers.
