<H3>Summary</H3></FONT><FONT FACE="Verdana" SIZE=2><P>HidGame is the WDM/HID minidriver for analog joysticks. This driver registers with the HID class driver and responds to IRPs put out by HIDclass. It informs HID class about the capabilities of the joystick and polls the joystick in response to a read IOCTL.</p>
<p>This driver is loaded in reponse to a "New hardware Found" Plug and Play (PnP) event,and consequently must have an entry in an .inf file that binds a PnP hardware ID to this driver. Gameport joysticks are not true PnP devices, so the user (through the GameControllers Control Panel) informs the system about a joystick attached to the gameport. An example of how a new joystick type can be created is provided in the accompanying .inf file. Once a user selects a joystick and gameport, the GameControllers CPL sends an IOCTL to the gameport bus driver (GameEnum), specifying the number of Axis / Buttons and a PnPHardware ID for the joystick. The Gameport Bus informs PnP of a new device arrival. PnP searches the system for a match for the hardwareID and loads the appropriate driver.<p>
<h3>BUILDING THE SAMPLE</h3></FONT><FONT FACE="Verdana" SIZE=2><P>
<p> Use standard Windows NT®/Windows® 2000 build tools. In the hidgame directory, type <B>build</B>. The build script will generate the driver Hidgame.sys </p>
<h3>TOOLS</h3></FONT><FONT FACE="Verdana" SIZE=2><P>
<p> You can test your driver using the the following apps/tools.<p><li><B>Game Controllers Control panel</b> from the Standard Control panel</p><p><li><b>Diquick.exe</b> (from the IDW directory or the Microsoft DirectX SDK at <a href=http://www.microsoft.com/directx/resources>Microsoft DirectX Resources</a>)</p><p><li><b>Shipping Microsoft DirectX games</b>
