title: CCID protocol command types
body: <p>based on the <a href="https://en.wikipedia.org/wiki/CCID_(protocol)" rel="nofollow">wikipedia</a>:</p>
  
  <p>According to the CCID specification by the USB standards work group, a CCID exchanges information through a host computer over USB by using a CCID message that consists of a 10-byte header followed by message-specific data.[2] The standard defines fourteen commands that the host computer can use to send data and status and control information in messages. Every command requires at least one response message from the CCID.</p>
  
  <p>I'm seeking detailed information about this hardware specification of the CCID protocol such as mentioned 14 commands,their equivalent APDU and etc.</p>
