title: How do I install the USB driver for Nexus One on Windows 7 for debugging purposes?
body: <p>I have implemented a simple Android application that I now would like to test on a real device. I have a Nexus One.</p>
  
  <p>In the Android Eclipse plugin, I have downloaded and installed the USB driver (revision 3) package. But when I connect my Nexus One to my PC (running Windows 7) using the USB cable, a message box pops up and shows that "No driver found" for "Nexus One".</p>

  <p>I have activated <strong>USB Debugging</strong> on my device. And when I run <code>adb devices</code> on my PC, it just prints <code>List of devices attached</code> and no devices are listed. And if I use <strong>Device Manages</strong> in Windows, and tries to update the driver for "Nexus One", I can not select a driver in the "driver directory" of <em>Android SDK</em>.</p>
  
  <p>How can I install a driver for Nexus One on Windows 7 so I can use it for USB debugging my Android applications on a real device?
