From the Nuc-144 user manual;

This nucleo has two usb connectors. CN1 on the stlink and CN13 for USB OTG.
Before we start, you should read 6.9 and 6.10 in Nuc-144 user man. UN1974
If you just want to get going fast, the STLINK creates a VCP (on CN1 connector).
The stlink connects to PD8/PD9 on the 767 (see schematic figure 16/17 in UM)
These are also the alternate pins for USART3 TX/RX.
If you are using Cube, enable USART 3. This enable PB10/PB
Then gotoeach of
PB10/PB10 pins
and crtl-click them, and CUBE shows the alternates, PD8/PD9.Reassign them.
Generate your project. Add the following to your main loop;
/* USER CODE BEGIN 2 */
uint8_t buffer[16] = ''Hello World
'';
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
HAL_UART_Transmit(&huart3, (uint8_t*)buffer, 13, 1000);
HAL_Delay(1000);
}
/* USER CODE END 3 */�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?in device manager, you find ports as shown below.
in this case, i have two nuc boards connected, one with normal stlink, and a 2nd with stlink reflashed with JLink firmware.
Goto your favorite terminal and connect your VCP comm port.
I think this is what your wanted to do. But....
If you really want to connect to CN13 using OTG.
The CN13 is dead, until you put some USB stuff in your project.
You have to setup USB_HS/FS and USB_CDC in your project.
Finally, going back to the UM, make sure you read the warning;
