title: adb error: more than one device - android
body: <p>I have 2 Android devices connected via usb to my pc</p>
  
  <p>now when i list devices i get this:</p>
  
  <pre><code>C:\Users\MBH&gt;adb devices
  List of devices attached
  0123456789ABCDEF        device
  0123456789ABCDEF        device
  </code></pre>
  
  <p>Both devices got the same serial number, or whatever this <strong>0123456789ABCDEF</strong> means.</p>
  
  <p><strong>The problem:</strong> I am not able to do anything in this case, neither pushing or pulling files, nor forwarding tcp ports. </p>
  
  <pre><code>C:\Users\MBH&gt;adb forward tcp:59900 tcp:59900
  error: more than one device/emulator
  
  C:\Users\MBH&gt;adb -s 0123456789ABCDEF forward tcp:59900 tcp:59900
  error: more than one device
  </code></pre>
  
  <p><strong>The question:</strong> is there anyway to connect or select device in different way? like device model number or something?</p>
