They should be installed in the following order: Then, use pnputil /i /a to install each of the desired driver packages. To install these driver packages, make sure that the target machine is in Test Mode, using bcdedit /set testsigning on.
The app and the contents of this sample can coexist, but on Windows 10 version 1703, to build the app with Visual Studio 2017, the computer cannot have the WDK installed. To learn how to pair a UWP app with a device, see Hardware access for Universal Windows Platform apps Additionally, you can also download a Universal Windows Platform app (UWP) that controls the OSR FX2 Learning Kit's device. This has been fixed for the Windows 10 Fall Creators Update.Įach of these solutions can be built with the latest WDK on Visual Studio 2015. You will see an error saying that the directive CopyINF does not work from extension INFs. Osrfx2_DCHU_extension_tight will not currently build on Windows 10 version 1703. They are intended to show a different way to use extension and component INFs depending on a project's needs. Here there is less flexibility with the base/component/extension relationship, but it ensures that the component INF is applied at the same time as the extension.īoth osrfx2_DCHU_extension_loose and osrfx2_DCHU_extension_tight provide the same functionality, so installing both on the same OSR FX2 device is unnecessary. Using CopyINF, both the extension and component INF are placed into one driver package (and one submission to DevCenter). This extension mimics the behavior of osrfx2_DCHU_extension_loose however, it does so in a tightly coupled manner. Osrfx2_DCHU_extension_tight: An extension INF for the OSR FX2 device. These two projects are loosely coupled, and can be installed in any order on the machine. There is also a component INF project that would be a separate submission to DevCenter, which runs some simple software. This extension modifies some registry settings originally specified by the base driver ( osrfx2_DCHU_base) and also uses AddComponent to create a Software Component. Osrfx2_DCHU_extension_loose: An extension INF for the OSR FX2 device. This includes the device driver, an upper filter driver for the device (a no-op), a Win32 User Service that controls lights on the device, and a console app that can control the device. Osrfx2_DCHU_base : The driver for the OSR FX2 Learning Kit.
The solutions are split into the following subdirectories: Each one represents a single submission on the Windows Hardware Dev Center dashboard. There are three Visual Studio solutions in this sample. For a detailed code walkthrough, see Universal Driver Scenarios. The sample uses the OSR FX2 learning kit. This sample illustrates the DCHU principles of universal driver design.
