Set the jumper near the reset button to E5V and use the E5V pin to supply the circuit with 5V. The USB port supply the debugger, but without enumeration it will not start the nucleo board.
Accepted Answer
You can put jumper on JP1 (leave jumper on U5V!) and use normal USB charger. It works without enumeration.
