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
