Hello, 

To monitor the connection and disconnection events of a USB device, you can implement the callback functions HAL_PCD_ConnectCallback() and HAL_PCD_DisconnectCallback(). These functions are triggered when the USB cable is connected and disconnected, respectively, allowing you to detect these events in device mode.

Please refer to the snipped code below to implement this function: 

#if (USE_HAL_PCD_REGISTER_CALLBACKS == 1U)
static void PCD_ConnectCallback(PCD_HandleTypeDef *hpcd)
#else
void HAL_PCD_ConnectCallback(PCD_HandleTypeDef *hpcd)
#endif /* USE_HAL_PCD_REGISTER_CALLBACKS */
{
  /* USER CODE BEGIN HAL_PCD_ConnectCallback_PreTreatment */

  /* USER CODE END HAL_PCD_ConnectCallback_PreTreatment */

  /* USER CODE BEGIN HAL_PCD_ConnectCallback_PostTreatment */

  /* USER CODE END HAL_PCD_ConnectCallback_PostTreatment */
}

#if (USE_HAL_PCD_REGISTER_CALLBACKS == 1U)
static void PCD_DisconnectCallback(PCD_HandleTypeDef *hpcd)
#else
void HAL_PCD_DisconnectCallback(PCD_HandleTypeDef *hpcd)
#endif /* USE_HAL_PCD_REGISTER_CALLBACKS */
{
  /* USER CODE BEGIN HAL_PCD_DisconnectCallback_PreTreatment */

  /* USER CODE END HAL_PCD_DisconnectCallback_PreTreatment */

  /* USER CODE BEGIN HAL_PCD_DisconnectCallback_PostTreatment */

  /* USER CODE END HAL_PCD_DisconnectCallback_PostTreatment */
}

 You can refer also to the example provided in STM32Cube firmware H7 in this link.
