title: ADB RSA Authorization Key dialog will not open
body: <p>so I'm trying to debug on my Nexus 6. I can't get the phone to open the RSA key auth. It works instantly on my friends macbook, with the same cable</p>
  
  <ul>
  <li>I have tried updating SDK.</li>
  <li>Installing and reinstalling the universal ADB driver; <a href="https://plus.google.com/103583939320326217147/posts/BQ5iYJEaaEH" rel="noreferrer">https://plus.google.com/103583939320326217147/posts/BQ5iYJEaaEH</a></li>
  <li>Checked that googles USB driver is installed and uptodate</li>
  <li>Rebooting both pc and phone several times.</li>
  <li>Killing and starting ADB from cmd.</li>
  <li>Switching between PTP and MTP modes</li>
  <li>And revoking USB debug auths on the phone...</li>
  </ul>
  
  <p>Anyone have any ideas? I'm almost pulling my hair out. :(</p>
