HID报告描述符解析器：如何找到“点击”位位置

我需要获取有关Wheell单击并从不同鼠标释放的信息。我在嵌入式设备上工作，可以访问原始形式的所有数据 - 字节流。HID报告描述符解析器：如何找到“点击”位位置

AFAIK所有传输的字节在HID报告描述符鼠标中描述。我有两个HID报告描述符和2点不同的鼠标传输的帧，但我不知道怎么去理解他们：

HID罗技：

End Collection C0

罗技帧4字节，首先为按钮：

00 00 00 00 : Button OFF (on release), X=0, Y=0, Whell=0 
01 00 00 00 : Button 1 ON, X=0, Y=0, Whell=0 
02 00 00 00 : Button 2 ON, X=0, Y=0, Whell=0

HID YACOSS：

YACOSS帧7个字节，第二个用于按钮：

01 00 00 00 00 00 00 Button 1 OFF (released), X=0, Y=0, Wheel=0, AC Pan=0 
01 01 00 00 00 00 00 Button 1 ON , X=0, Y=0, Wheel=0, AC Pan=0 
01 02 00 00 00 00 00 Button 2 ON , X=0, Y=0, Wheel=0, AC Pan=0

报告描述符格式在Device Class definiton for HID中进行了说明。小鼠也在HID使用表格doc中报道。所有这一切都可以在一个usb.org HID页面 - >http://www.usb.org/developers/docs/hidpage/

我博客上嵌入HID，包括报告描述，在这里 - >http://www.circuitsathome.com/category/mcu/arduino/usb-shield/hid

另外，如果你只需要一个特定的功能，从鼠标，如X，Y，轮子和3个按钮，可以将其初始化为启动设备。任何鼠标都将具有相同的报告结构（请参阅引导鼠标），并且可以将其硬编码到您的应用程序中。
