how to find out broadcast receiver is called?

Question

I'm trying to use usb serial port but all example I've seen use broadcast receiver. in their code they give a pending intent to UsbSeialManager.requestPermission(pi). now i want to know if there is a way to see if onReceive() is called or not. and to wait for it. I need a method that return correct usb(onReceive() is called) PS I'm making a class for each connected usb.

Within the help of Log.d("key","value"); you can print the log to identify that onReceive() is called or not
