title: Cannot see Nexus 6P for debugging
body: <p>I'm using Windows 10, a Dell XPS 13, and v1.4.1 of Android Studio.  I have SDK Tools 24.4.1 installed as well as Google USB Driver 11.
  #
  On the phone I have USB debugging enabled and can see the device in File Explorer (i.e. documents, pictures, etc.).</p>
  
  <p>But the device never shows up using <code>adb devices</code>, nor in Android Studio.</p>
  
  <p>I've never had this much trouble getting an Android device debugging before, but I don't know if it's Marshmallow or the Nexus 6P that's to blame. More importantly, I've no idea what to do at this point to get it debugging.</p>
