title: Windows Phone deploy Issue
body: <p>I have a strange issue that I can not seem to find any record of but it has now happened to me on two separate machines! I am building Windows Phone 8.1 apps and testing them on a physical device. This works fine for a time until at some point with no warning i am unable to deploy to the phone and the console shows the errors below!</p>
  
  <pre><code>Error : DEP6100 : The following unexpected error occurred during bootstrapping stage 'Connecting to the device '30F105C9-681E-420b-A277-7C086EAD8A4E'.': SmartDeviceException - Deployment failed because no Windows Phone was detected. Make sure a phone is connected and powered on. 
  
  Error : DEP6200 : Bootstrapping 'Device' failed. Device cannot be found. Deployment failed because no Windows Phone was detected. Make sure a phone is connected and powered on.

  <p>Now this would lead me to believe that the cable has fallen out or its just become disconnected however it hasn't and im sure of that because i can still use it as a storage device to transfer pictures. Restarting the devices has zero effect and the only thing that worked on the first machine i tried was reformatting the pc and starting from scratch which i really dont have the time to do again!</p>
