title: Why is Eclipse's Android Device Chooser not showing my Android device?
body: <p>I am using the Android plugin for Eclipse, and when I try to run my program using a real device through the <em>Android Device Chooser</em>, my phone is not listed as a device. I have updated Eclipse, all of the Android packages, and the USB driver, but it still isn't showing up. My phone is running Android 2.1, which is also the target version listed in the Eclipse project.</p>
  
  <p>Also it happens that the device shows up as an unknown target and the serial number as question marks as shown in the screenshot.</p>
