title: no permissions error on adb devices
body: <p>Every time I reboot my Ubuntu 17.10 machine I get this error when I run <code>adb devices</code>:</p>
  
  <pre><code>List of devices attached
  8XV7N15A20003222    no permissions (verify udev rules); see [http://developer.android.com/tools/device.html]
  </code></pre>
  
  <p>And to fix it all I do is run:</p>
  
  <pre><code>sudo udevadm control --reload
  </code></pre>
  
  <p>And then I unplug the phone and plug it back in because flipping usb debug on and off on the settings isn't enough. Unplugging and plugging back in doesn't fix it unless I run that command. </p>
  
  <p>What can I do to fix this permanently? This is a Nexus 6P. </p>
  
  <p>Edit: I don't think this is a duplicate because restarting adb doesn't fix it like on that linked post. I've also already edited the udev rules. </p>
  
  <p>Edit: One more thing, this only happens to my 6P. I have several other phones connected (Nexus 6,4,5, some samsung, motorola, etc) and none of them have that issue. </p>
