    command.c: returns IFD_ERROR_INSUFFICIENT_BUFFER
    
    If the reader returns an error (cancel or timeout) that the driver
    reports as SW=0x6400 or SW=0x6401 and the RX buffer is less than 2
    bytes the driver now returns IFD_ERROR_INSUFFICIENT_BUFFER instead of
    IFD_COMMUNICATION_ERROR.
    
    Thanks to Godfrey Chung and the ACS driver version 1.1.1 for idea.
