I am using Visual Studio 2013 on Windows 8. I have got three Windows Phone devices, lumia 620, 920, 1320 and these are all developer unlocked devices. The 620 device has got Windows Phone 8.1 preview installed. Whenever I'm trying to deploy a WP8 project to this 620, debug windows gives me this error:
1>Deployment of application to device failed.
1>Error: Deployment failed because no Windows Phone 8 phone was detected. Make sure a phone is connected and powered on.
========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========
I have tried deploying after rebooting the phone, VS 2013 and even my PC, but failed in every case.
Please share any idea what may have caused this issue to occur or help me on how can I solve this issue. Thanks in advance.
As @aloisdg said in a comment, you can fix the problem by unplugging your phone, going to 'Control Panel->Hardware and Sound->Devices, removing your phone, then connecting your phone by USB.
