title: ADB with two nexus devices connected
body: <p>I have two devices, a Nexus 10 and a Nexus 7 tablets which I connect to my PC via two separate USB cables.</p>
  
  <p>Windows Explorer pops up the Autoplay window for both of them when I do so they are recognised as devices.</p>
  
  <p>I revoke USB debugging authorisations for both devices.</p>
  
  <p>I plug Nexus 7 and authorise the computer to be the debugger.</p>
  
  <pre><code>List of devices attached
  015d2d426b2ffe15        device
  </code></pre>
  
  <p>I disconnect Nexus 7 and connect Nexus 10.</p>
  
  <p>I authorise the device and everything is fine.</p>
  
  <pre><code>List of devices attached
  R32CB03S65R     device
  </code></pre>
  
  <p>I connect Nexus 7 again (without plugging out Nexus 10) and the device is not even recognised by ADB.</p>
  
  <p>I restart the ADB server and no device is displayed and both devices need me to reauthorise the same computer. Even if I do no device gets recognised.</p>
  
  <p>chome://inspect shows both devices, ADB and Eclipse are showing only one.</p>
  
  <p>If by chance, both devices become visible in ADB, after a lot of random plugging in and out, I try to android:deploy my maven app in Eclipse. On nexus 7 it uninstalls the old one and installs the new one fine, but on nexus 10 I get a InstallException: TimeoutException 
  (with timeout option set to 15s)</p>
  
  <p>If I have nexus 10 connected and I connect nexus 7, nexus 10 disappears from the list and nexus 7 doesn't show up either.</p>
  
  <p>Have anyone come across anything like this before?
  Is there any special configuration needed to be able to work with both devices at the same time?</p>
  
  <p>Any help greatly appreciated.</p>
