HID報告描述符解析器：如何找到「點擊」位位置

我需要獲取有關Wheell單擊並從不同鼠標釋放的信息。我在嵌入式設備上工作，可以訪問原始形式的所有數據 - 字節流。HID報告描述符解析器：如何找到「點擊」位位置

AFAIK所有傳輸的字節在HID報告描述符鼠標中描述。我有兩個HID報告描述符和2點不同的鼠標傳輸的幀，但我不知道怎麼去理解他們：

HID羅技：

羅技幀4字節，首先爲按鈕：

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

YACOSS幀7個字節，第二個用於按鈕：

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

報告描述符格式在Device Class definiton for HID中進行了說明。小鼠也在HID使用表格doc中報道。所有這一切都可以在一個usb.org HID頁面 - >http://www.usb.org/developers/docs/hidpage/

我博客上嵌入HID，包括報告描述，在這裏 - >http://www.circuitsathome.com/category/mcu/arduino/usb-shield/hid

另外，如果你只需要一個特定的功能，從鼠標，如X，Y，輪子和3個按鈕，可以將其初始化爲啓動設備。任何鼠標都將具有相同的報告結構（請參閱引導鼠標），並且可以將其硬編碼到您的應用程序中。
