Ux_Device_CDC_ACM Usb port not recognize in Device manager

[MDeva.1]

Hello,

I am working on Nucleo-h745ziq board. The example provide in cubemx of Ux_Device_CDC_ACM accordingly I create the example for Nucleo-h745ziq board. The changes I make that instead of HS I select Fs mode because board support the FS mode and disable the MPU protection because it gives problem for CM4 core. When I connect two usb only STLINK Port recognize user USB port is not get updated. I share the setup things,

static void MX_USB_OTG_FS_PCD_Init(void)

{

 /* USER CODE BEGIN USB_OTG_FS_Init 1 */

 memset(&hpcd_USB_OTG_FS, 0x0, sizeof(PCD_HandleTypeDef));

 /* USER CODE END USB_OTG_FS_Init 1 */

 hpcd_USB_OTG_FS.Instance = USB_OTG_FS;

 hpcd_USB_OTG_FS.Init.dev_endpoints = 9;

 hpcd_USB_OTG_FS.Init.speed = PCD_SPEED_FULL;

 hpcd_USB_OTG_FS.Init.dma_enable = DISABLE;

 hpcd_USB_OTG_FS.Init.phy_itface = USB_OTG_EMBEDDED_PHY;

 hpcd_USB_OTG_FS.Init.Sof_enable = DISABLE;

 hpcd_USB_OTG_FS.Init.low_power_enable = DISABLE;

 hpcd_USB_OTG_FS.Init.lpm_enable = DISABLE;

 hpcd_USB_OTG_FS.Init.battery_charging_enable = ENABLE;

 hpcd_USB_OTG_FS.Init.vbus_sensing_enable = DISABLE;

 hpcd_USB_OTG_FS.Init.use_dedicated_ep1 = DISABLE;

 if (HAL_PCD_Init(&hpcd_USB_OTG_FS) != HAL_OK)

 {

  Error_Handler();

 }

 }

void MX_USB_Device_Init(void)

{

 HAL_PWREx_EnableUSBVoltageDetector();

 MX_USB_OTG_FS_PCD_Init();

 HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x200);

 HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, 0x10);

 HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 2, 0x10);

 HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 3, 0x20);

 ux_dcd_stm32_initialize((ULONG)USB_OTG_FS, (ULONG)&hpcd_USB_OTG_FS);

 HAL_PCD_Start(&hpcd_USB_OTG_FS);

  }

Why the port is not get updated the Device driver? Can you help me. Because I am newly work on Azure Rtos I don't have much knowledge of it.

Have a look at the example "Ux_Device_HID_CDC_ACM" provided within the AZRTOS-H7 pack it is using the STM32H747-DK board similar to the one you are using.
