作为一项学习练习,我正在尝试在Windows 7 64位上为有线XBox 360控制器编写过滤器驱动程序。该控制器显示为HID操纵杆,因此它看起来应该是直截了当的。
我为我的鼠标制作了一个示例过滤器驱动程序,用于交换左右鼠标按钮。这是基于WDK附带的moufiltr和firefly样本。但是,我无法将此示例转换为XBox 360控制器。
当我插入控制器时,设备管理器中会出现3个不同的设备:
我应该将我的驱动程序中的哪一个附加到?
使用鼠标过滤器驱动程序,我可以关注firefly示例中的installation directions:右键单击设备管理器中的鼠标,选择“更新驱动程序”。使用XBox 360控制器,我不确定我应该为哪个设备安装驱动程序。或者他们是否都独立与硬件交谈,我需要为每一个安装一个过滤器?
我应该注意,我已经尝试将过滤器驱动程序附加到3个设备中的每个设备,以便打印出我的过滤器驱动程序可用的IOCTL。对于“USB人机接口设备”,我的过滤器没有收到IOCTL。
对于符合HID标准的游戏控制器,它收到了:
对于适用于Windows的Xbox 360控制器,它会收到一堆我无法追踪符号名称的IOCTL:
不幸的是,我仍然不知道我应该尝试过滤哪个设备。 (我希望他们中的一个会收到相当于IOCTL_INTERNAL_MOUSE_CONNECT的操纵杆,但情况似乎并非如此。)
答案 0 :(得分:0)
我认为你想过滤内部IOCTL(特别是IOCTL_HID_GET_INPUT_REPORT / IOCTL_HID_READ_REPORT)
您可能已经过滤了EvtIoDeviceControl尝试EvtIoInternalDeviceControl并查找读取/获取输入报告ioctl,这将来自任何想要读取操纵杆事件的系统服务。
一旦你设法过滤了正确的ioctl,你需要查看该操纵杆的报告描述符,以找出如何解释(然后修改)数据。

从xusb22.sys XInputRequestDispatcher :: Dispatch():
0x80006000 DispatchGetInformation((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer, (ULONG)ioctlCode);
0x8000A010 DispatchSetState((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000A01C DispatchPowerDownDevice((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000E004 DispatchGetCapabilities((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000E008 DispatchGetLedState((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer)
0x8000E00C DispatchGetState((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000E014 DispatchWaitForGuideButton((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer)
0x8000E018 DispatchGetBatteryInformation((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000E020 DispatchGetAudioDeviceInformation((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
0x8000E3AC DispatchWaitForInput((XInputRequestServicers *)this, (struct XenonBusInformation *)&v6, (RequestBuffers*)buffer);
0x8000E3FC DispatchGetInformationEx((XInputRequestServicers *)this, (WDFREQUEST)request, (RequestBuffers*)buffer);
因此,我们可以反转工程师代码:
