USB滑鼠鍵盤資料格式以及按鍵鍵值

網上相關的資料很多 ，有點分散，我沒事就邊學習邊整理了下，供大家參考``：

滑鼠傳送給PC的資料每次4個位元組
BYTE1 BYTE2 BYTE3 BYTE4
定義分別是：
BYTE1 –
|–bit7: 1 表示 Y 座標的變化量超出－256 ~ 255的範圍,0表示沒有溢位
|–bit6: 1 表示 X 座標的變化量超出－256 ~ 255的範圍，0表示沒有溢位
|–bit5: Y 座標變化的符號位，1表示負數，即滑鼠向下移動
|–bit4: X 座標變化的符號位，1表示負數，即滑鼠向左移動
|–bit3: 恆為1
|–bit2: 1表示中鍵按下
|–bit1: 1表示右鍵按下
|–bit0: 1表示左鍵按下
BYTE2 – X座標變化量，與byte的bit4組成9位符號數,負數表示向左移，正數表右移。用補碼錶示變化量
BYTE3 – Y座標變化量，與byte的bit5組成9位符號數，負數表示向下移，正數表上移。用補碼錶示變化量
BYTE4 – 滾輪變化。
由於手上沒有USB滑鼠，對BYTE1的4-7位沒有測試，對於BYTE2 BYTE3做個測試，BYTE1的4-7全為0的時候，BYTE2 BYTE3的正負表示滑鼠移動方向

鍵盤傳送給PC的資料每次8個位元組
BYTE1 BYTE2 BYTE3 BYTE4 BYTE5 BYTE6 BYTE7 BYTE8
定義分別是：
BYTE1 –
|–bit0: Left Control是否按下，按下為1
|–bit1: Left Shift 是否按下，按下為1
|–bit2: Left Alt 是否按下，按下為1
|–bit3: Left GUI 是否按下，按下為1
|–bit4: Right Control是否按下，按下為1
|–bit5: Right Shift 是否按下，按下為1
|–bit6: Right Alt 是否按下，按下為1
|–bit7: Right GUI 是否按下，按下為1
BYTE2 – 暫不清楚，有的地方說是保留位
BYTE3–BYTE8 – 這六個為普通按鍵
鍵盤經過測試。
例如：鍵盤傳送一幀資料 02 00 0x04 0x05 00 00 00 00
表示同時按下了Left Shift + ‘a’+‘b’三個鍵
