鼠标发送给PC的数据每次4个字节
BYTE1 BYTE2 BYTE3 BYTE4
定义分别是：
BYTE1 --
|--bit7: 1 表示 Y 坐标的变化量超出－256 ~ 255的范围,0表示没有溢出
|--bit6: 1 表示 X 坐标的变化量超出－256 ~ 255的范围，0表示没有溢出
|--bit5: Y 坐标变化的符号位，1表示负数，即鼠标向下移动
|--bit4: X 坐标变化的符号位，1表示负数，即鼠标向左移动
|--bit3: 恒为1
|--bit2: 1表示中键按下
|--bit1: 1表示右键按下
|--bit0: 1表示左键按下
BYTE2 -- X坐标变化量，与byte的bit4组成9位符号数,负数表示向左移，正数表右移。用补码表示变化量
BYTE3 -- Y坐标变化量，与byte的bit5组成9位符号数，负数表示向下移，正数表上移。用补码表示变化量
BYTE4 -- 滚轮变化。
由于手上没有USB鼠标，对BYTE1的4-7位没有测试，对于BYTE2 BYTE3做个测试，BYTE1的4-7全为0的时候，BYTE2 BYTE3的正负表示鼠标移动方向
键盘发送给PC的数据每次8个字节
BYTE1 BYTE2 BYTE3 BYTE4 BYTE5 BYTE6 BYTE7 BYTE8
定义分别是：
BYTE1 --
|--bit0: Left Control是否按下，按下为1
|--bit1: Left Shift 是否按下，按下为1
|--bit2: Left Alt 是否按下，按下为1
|--bit3: Left GUI 是否按下，按下为1
|--bit4: Right Control是否按下，按下为1
|--bit5: Right Shift 是否按下，按下为1
|--bit6: Right Alt 是否按下，按下为1
|--bit7: Right GUI 是否按下，按下为1
BYTE2 -- 暂不清楚，有的地方说是保留位
BYTE3--BYTE8 -- 这六个为普通按键
键盘经过测试。
例如：键盘发送一帧数据 02 00 0x04 0x05 00 00 00 00
表示同时按下了Left Shift + ‘a’+‘b’三个键
