title: adb can't find my device (sony xperia J)
body: <ol>
  <li>I use windows 7 64 bit</li>
  <li>My phone is a Sony Xperia J</li>
  <li>my phone is in debugging mode</li>
  <li>drivers for my phone are installed</li>
  <li>'adb devices' returns: "List of devices attached" with nothing else</li>
  <li>I have removed all related software and installed it again</li>
  </ol>
  
  <p>There are quite a lot of other things I tried already, but since I've been trying to solve this for 2 days already, I basically already tried every possible solution that is out there on the internet. Please help.</p>
