Read micro USB and add listener

Good day

Is micro USB same as USB described in docs ?

Ask because i cant add listener to read data incoming via micro usb

function onInit() {
  // fire event when receive data via general usb port
  USB.on('data', function (data) {
    digitalWrite(LED3,1);
    print("<USB> "+data);
  });
}

Then connect to PC and send data using special tools to COM port, for example:

1+1

and receive only

2

As we see, listener did not fire ...
