title: ADB shows Motorola Xoom as offline when connected
body: <p>I have a Wi-Fi Motorola Xoom that I am connecting via ADB for development. I am seeing an intermittent problem where the device (with ID number) shows up in the adb devices list, but will present as being offline.</p>
  
  <p>The device and computer both show the tablet as being connected. I've tried a combination of rebooting each device and swapping USB ports, but the only thing that solves the issue is switching out the cable. Furthermore, a cable that I used yesterday doesn't work today -- I am having to use a previously non-functioning cable to connect.</p>
  
  <p>Is this a driver issue? Device port issue? I have seen this issue with several versions of the Motorola drivers as well as the PdaNet drivers. I am currently using Motorola Mobile Drivers 4.7.1.</p>
