How to write your first USB client driver (UMDF) • • 12 minutes to read • Contributors • In this article In this topic you'll use the USB User-Mode Driver template provided with Microsoft Visual Studio 2012 to write a user-mode driver framework (UMDF)-based client driver. After building and installing the client driver, you'll view the client driver in Device Manager and view the driver output in a debugger. UMDF (referred to as the framework in this topic) is based on the component object model (COM). Every framework object must implement and its methods,,, and, by default. The AddRef and Release methods manage the object's lifetime, so the client driver does not need to maintain the reference count. The QueryInterface method enables the client driver to get interface pointers to other framework objects in the Windows Driver Frameworks (WDF) object model. Framework objects perform complicated driver tasks and interact with Windows. Certain framework objects expose interfaces that enable a client driver to interact with the framework. A UMDF-based client driver is implemented as an in-process COM server (DLL), and C++ is the preferred language for writing a client driver for a USB device. Typically, the client driver implements several interfaces exposed by the framework. This topic refers to a client driver-defined class that implements framework interfaces as a callback class. After these classes are instantiated, the resulting callback objects are partnered with particular framework objects. This partnership gives the client driver the opportunity to respond to device or system-related events that are reported by the framework. Whenever Windows notifies the framework about certain events, the framework invokes the client driver's callback, if one is available. Otherwise the framework proceeds with the default processing of the event. The template code defines driver, device, and queue callback lasses. For an explanation about the source code generated by the template, see. Prerequisites For developing, debugging, and installing a user-mode driver, you need two computers: • A host computer running Windows 7 or a later version of the Windows operating system. Portable Media Serial Number ServiceThe host computer is your development environment, where you write and debug your driver. • A target computer running the version of the operating system that you want to test your driver on, for example, Windows 8. Pdf Printer Driver Windows 10The target computer has the user-mode driver that you want to debug and one of the debuggers. In some cases, where the host and target computers are running the same version of Windows, you can have just one computer running Windows 7 or a later version of the Windows. This topic assumes that you are using two computers for developing, debugging, and installing your user mode driver. Before you begin, make sure that you meet the following requirements: Software requirements • Your host computer has Visual Studio 2012. • Your host computer has the latest Windows Driver Kit (WDK) for Windows 8. Free Pdf Driver Windows 7The kit include headers, libraries, tools, documentation, and the debugging tools required to develop, build, and debug a USB client driver. You can get the latest version of the WDK from. • Your host computer has the latest version of debugging tools for Windows. You can get the latest version from the WDK or you can. • If you are using two computers, you must configure the host and target computers for user-mode debugging. For more information, see. Hardware requirements Get a USB device for which you will be writing the client driver. In most cases, you are provided with a USB device and its hardware specification.
