title: Cordova: Keyboard events when using external barcode reader with keyboard emulation
body: <p>I´m developing an android app with cordova latest version to use an android device with a Barcode reader connected through USB with keyboard emulation data transfer. I'm trying to handle the keydown events triggered by the barcode reader every time it reads a code, but the system fires the handle function but i can't find the event data telling me the keycodes.</p>
  
  <p>I'm using that code on application starting:</p>
  
  <pre><code>document.addEventListener('keydown',
      function(e){
      //Here should come the data but e.keycode everytimes comes with 0
  });
  </code></pre>
  
  <p>AS I'm saying on the above code the event var (e) always come with no information about the event triggered, is like a regular event object but comes with no relevant info about the key event.</p>
  
  <p>I will be very gratefull with any help or suggestion.</p>
  
  <p>Thanks in advance</p>
