title: USB-Programming on iPhone
body: <p>all i want to do is to sent/receive data over the USB Port.
  With the official SDK it is not possible - apart from MFi.</p>
  
  <p>Which other methods to communicate wired with other devices are possible and would you propose?</p>
  
  <p>Many Thanks in advance!</p>
