title: adb devices list empty -- Snow Leopard
body: <p>I'm running into an issue with the android SDK where it doesn't recognize devices plugged in via usb:</p>
  
  <pre><code>$adb start-server                                 
  * daemon not running. starting it now on port 5037 *
  * daemon started successfully *
  $adb devices                                      
  List of devices attached
  </code></pre>
  
  <p>(list is empty, other sdk tools don't recognize the devices either)</p>
  
  <p>According to the SDK documentation, on Mac OS X, this should "just work". <a href="http://developer.android.com/guide/developing/device.html#setting-up" rel="noreferrer">(Setting up a Device for Development)</a></p>
  
  <p>It's worked for me in the past, but seems to have just stopped. Is there an OS X solution to this problem? (On other operating systems presumably you have to fiddle with USB drivers)</p>
  
  <p>Have tried:</p>
  
  <ul>
  <li>Power cycling machine and device</li>
  <li>Switching USB ports Unplugging all</li>
  <li>USB except for the sole (non-split)</li>
  <li>cable to the device Multiple cables</li>
  </ul>
