Debug breakpoints in VS

I can´t connect my Android device to Visual Studio. I have write in cmd:

Adb start-server
Adb usb

I have listed the devices and this appears correctly with permission.

The device doens´t apper (when the aplication starts) in visual studio, however all tools in unity are working perfectly.

I have also tried:

Adb kill-server
Adb startServer
Adb connect MyIp:5555

But it doen´t appear in visual.

What is the problem?
Thanks in advance.

First, reboot and restart everything (computer, android, etc).

I have restarted several times and it doesn´t work
