USB鼠标键盘数据格式以及按键键值

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

第一列10进制键值，第二列16进制键值，第四列是按键
