I am using K22FN512VLH12 MCU in our upcoming product. For debugging purposes, I was using UART TX and RX pins till now and I was using external USB to UART converter to connect to my Laptop/PC and look at the debug logs. I am thinking why cant I use USB0_DB and USB0_DM pins for comm pins between my laptop and MCU. I saw the same thing in Teensy3.1 schematics. but I am unsure about how to use it. Can someone please provide me guidelines on this. It will be of great help.
