Error: Deployment failed because Windows Phone 8 was not detected

Question

I use Visual Studio 2013 on Windows 8. I have three Windows Phone devices, lumia 620, 920, 1320, and all of these are unlocked developer devices. The 620 has a preview of Windows Phone 8.1. Whenever I try to deploy a WP8 project for this 620, the debug windows give me this error:

1> Failed to deploy the application to the device.
1> Error: Deployment failed because Windows Phone 8 was not detected. Make sure the phone is connected and turned on.
========== Deployment: 0 succeeded, 1 failed, 0 skipped ==========

I tried deployment after rebooting the phone, VS 2013 and even my PC, but failed in each case.

Please share an idea of ​​what might have caused this problem, or help me on how I can solve this problem. Thanks in advance.

Answer 1

As @aloisdg noted in a comment, you can fix the problem by turning off the phone, going to "Control Panel" - "Hardware and Sound" - "Devices", deleting the phone, and then connecting your phone to USB.

Answer 2

So, before you deploy the application to the device, check if the device is recognized on your PC / laptop.

Try connecting the device to a different port. Have you tried another cable for the device.

Hope this helps!

Answer 3

Problem May be with any port driver. I also came across this by solving it using the following steps.

• Check all ports on your laptop / PC.

• Go to Device Manager → Universal Serial Bus Controller → Delete the one that has a yellow label.

• Go to Action → Scan for hardware changes. The driver will automatically install.

• Then run the application :)
