c++ - 报告描述符和报告数据结构不正确？

转载作者：行者123 更新时间：2023-11-30 17:16:04

我正在研究一个 HID 报告描述符，我通过修改此处的示例代码来使用它: https://code.msdn.microsoft.com/WudfVhidmini-Sample-b304f83a/sourcecode?fileId=42918&pathId=205101617 (该链接打开queue.cpp文件，这是我的驱动程序的大部分读/写代码和默认的隐藏报告描述符所在的位置)。到目前为止，我的驱动程序中更新的报告描述符是(截至 2015 年 5 月 11 日):

  HID_REPORT_DESCRIPTOR           G_DefaultReportDescriptor[] = {

这是我当前使用的示例附带的默认报告结构(直到我弄清楚可以在其中更改什么):

typedef struct _HIDMINI_INPUT_REPORT {

    UCHAR ReportId;   

    UCHAR Data; 

} HIDMINI_INPUT_REPORT, *PHIDMINI_INPUT_REPORT;

//
// output to device from system
//
typedef struct _HIDMINI_OUTPUT_REPORT {

    UCHAR ReportId;   

    UCHAR Data; 

    USHORT Pad1;

    ULONG Pad2;

} HIDMINI_OUTPUT_REPORT, *PHIDMINI_OUTPUT_REPORT;

我的问题有四:

我需要将 4 个鼠标设备的数据从控件集合(到达鼠标设备注释开始之前的第一个集合)向下传递到鼠标集合中。我将如何编写报告描述符来执行此操作，或者我是否需要代码来执行此操作？
我的报告结构代码如何查找从 Windows.Devices.HumanInterfaceDevice 读取/写入控制结构？
我是否应该像 vmulti 那样发送每个报告描述符(除了在一个循环中全部发送)？
如果我想为多点鼠标 SDK 或其他多鼠标应用程序模拟/仿真鼠标设备，需要执行哪些操作？ (将输入发送到多鼠标应用程序)

注意:我计划使用 https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.humaninterfacedevice.aspx从上面定义的 4 个鼠标设备读取/写入的类函数，这就是为什么我要费尽心思去弄清楚这些东西。但 msdn 上的类(class)明确指出我无法直接写入鼠标设备。如果是这样的话，我就不会写在这里了。 如果出现问题:是的，这是关于将输入注入(inject)到鼠标集合中，以便我可以让它们与多鼠标应用程序一起使用。上面指向 WudfVhidmin-Sample 的链接不是我的代码但我用来编写驱动程序的示例。

如果我取出第一个结束集合注释之前的部分，它会创建三个鼠标设备，但仅此而已。

最佳答案

听起来您想要定义一个报告描述符来容纳四个物理鼠标指针(至少这是您问题的一部分？)。 HID 报告描述符规范允许“实例”的概念，因此我认为尝试类似以下报告描述符的内容可能值得研究。 我不知道它在实践中是否有效，但它基于 HID Usage Tables 1.12 specification 中“附录 A.5 控件的多个实例”中的一个(相当不稳定的恕我直言)示例。。

据我所知，没有办法定义一个实例一次并以某种方式生成四个实例。您似乎必须为每个实例复制报告描述符。

无论如何都值得一试。

以下内容是由我不久前编写的一些代码生成的，名为 hidrdd帮助我解码 HID 报告描述符:
