KMDF based firmware update drivers can send the vendor specific commands to perform the firmware update.

#SCT DEVICE UPDATER WILL NOT READ DEVICE DRIVER#

For example, the UMDF based filter driver for a camera would use Camera APIs to perform the firmware update. UMDF based firmware update drivers can use the device specific APIs or issue the control transfers directly to access the USB device to perform the firmware update. On receiving the notification, the filter driver should post a work-item that would perform the firmware update. The firmware update filter driver for a RGB camera would register for KSCATEGORY_VIDEO_CAMERA. When the EVT_WDF_DEVICE_D0_ENTRY callback of the WDF filter driver is called at a later point, the filter driver must register for device interface change notifications using CM_Register_Notification or IoRegisterPlugPlayNotification (UMDF or KMDF) to listen to the device interface class the USB device will register the device into. Because there is no necessity for updating the firmware as the device has the expected firmware.

Then, the filter driver will insert itself into the device stack by returning success to AddDevice callback.Įlse, the filter driver will not insert itself into the device stack.

The firmware version is not available in the device HW registry key If the device firmware version and the filter driver expected firmware version are different, or The device firmware should have placed the firmware version using the MSOS descriptor onto the device HW registry key. From this routine, the WDF filter driver will get for the device firmware version from the device HW registry key. While installing the driver update package, the firmware update WDF filter driver's AddDevice routine will be called.

The driver update package on the Windows Update server will contain:Ī firmware update WDF lower filter driverĪn extension INF to install the firmware update WDF lower filter driver This filter driver will perform the firmware update. In this method, a lower filter driver to the USB device driver will be installed as part of driver update process. 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.
