Connecting both the ESP and the USB on the same serial lines creates a electrical conflict on the Tx line (towards the PIL-Box IC) - the strongest wins. I would recommend to insert a e.g. 10k resistor in the Tx line from the USB, so the ESP will take precedence softly, and if not present the USB will still operate.
