After the new firmware package for STM32WB, v1.2, I am not able to see the STM32WB on COM port after running a simple USB CDC code to enable serial communication.

	 sprintf(dataOut, "HelloWorld");
	 //CDC_Transmit_FS(( uint8_t * )dataOut, strlen( dataOut ));
	 USBD_CDC_SetTxBuffer(&hUsbDeviceFS, ( uint8_t * )dataOut, strlen( dataOut ));
	 USBD_CDC_TransmitPacket(&hUsbDeviceFS);
	 HAL_Delay(1000);
 }
 /* USER CODE END 3 */
}

The mentioned code should send "HelloWorld" every second over USB. I have connected both the USBs to STM32WB. I able to see one port which is used to for debugging/downloading but can't see the other one. Anyone with any idea?
