title: Android device not seen by ADB but accessible from Windows XP
body: <p>I just bought a new Nexus 7 tablet and I am trying to put my first Java application on it. However, I am stuck at a very basic point: ADB does not see my device. When I check on my working station, Windows perfectly detects the tablet, I switched the USB port and every one make appear the device but ADB still cannot see it. I rebooted and it is still not working. Any idea about this?</p>

  <p>There was actually two problems. First, I had not activated the <strong>USB debugging</strong> mode. This was the reason why I could use the tablet from the working station (as a simple multimedia player) even though the correct USB driver was not installed.</p>
  
  <p>Second, the driver was not detected by Windows XP (even we I specified the correct repository to search for it). The problem was solved by following the procedure described by <a href="https://stackoverflow.com/users/342605/adamp">adamp</a></p>
