connecting. It is empty character string or any character string when USB connecting.
Return result: the result is zero, which shows the action is correct, others are wrong.
Explanation：It needs to call ”OpenReader” function before operating the reader
2. CloseReader
Function prototype：short loseReader (HANDLE h om)
Function explanation：close the reader
Input parameter:
h om-- Handle
