我用做全速，不做高速，使用了内部的PHY，竟然无法枚举？
使用demo修改的，在USB 的D+上加了一个上拉，  使用官方的HID demo修改，FS USB 接口可以识别，为啥HS接口无法识别，调试发现USB会发生复位中断，后面就没有任何中断了！代码如下：
  hpcd.Instance = USB_OTG_HS;
  hpcd.Init.dev_endpoints = 4;
  hpcd.Init.use_dedicated_ep1 = 0;
  hpcd.Init.ep0_mps = 0x40;
  
  /* Be aware that enabling DMA mode will result in data being sent only by
     multiple of 4 packet sizes. This is due to the fact that USB DMA does
     not allow sending data from non word-aligned addresses.
     For this specific application, it is advised to not enable this option
     unless required. */
  hpcd.Init.dma_enable = 0;
  hpcd.Init.low_power_enable = 0;
  //use inter phy!! 使用内部PHY
  hpcd.Init.phy_itface = PCD_PHY_EMBEDDED;
  hpcd.Init.Sof_enable = 0;
  hpcd.Init.speed = PCD_SPEED_FULL;
  hpcd.Init.vbus_sensing_enable = 0;
  /* Link The driver to the stack */
  hpcd.pData = pdev;
  pdev->pData = &hpcd;
  /* Initialize LL Driver */
  HAL_PCD_Init(&hpcd);
  
  HAL_PCDEx_SetRxFiFo(&hpcd, 0x80);
  HAL_PCDEx_SetTxFiFo(&hpcd, 0, 0x40);
  HAL_PCDEx_SetTxFiFo(&hpcd, 1, 0x80);



IO设置：
{
    /* Configure USB H GPIOs */
    __HAL_RCC_GPIOB_CLK_ENABLE();

         /* Configure DM DP Pins */
    GPIO_InitStruct.Pin = (GPIO_PIN_14 | GPIO_PIN_15);
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF10_OTG_HS;   
    HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
       
    /* Enable USB HS Clocks */
        __HAL_RCC_USB_OTG_HS_CLK_ENABLE();
    //__HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE();

    /* Set USBHS Interrupt priority */
    HAL_NVIC_SetPriority(OTG_HS_IRQn, 5, 0);

    /* Enable USBHS Interrupt */
    HAL_NVIC_EnableIRQ(OTG_HS_IRQn);

    if(hpcd->Init.low_power_enable == 1)
    {
      /* Enable EXTI Line 20 for USB wakeup*/
      __HAL_USB_OTG_HS_WAKEUP_EXTI_CLEAR_FLAG();
      __HAL_USB_OTG_HS_WAKEUP_EXTI_ENABLE_RISING_EDGE();
      __HAL_USB_OTG_HS_WAKEUP_EXTI_ENABLE_IT();   

      /* Set EXTI Wakeup Interrupt priority*/
      HAL_NVIC_SetPriority(OTG_HS_WKUP_IRQn, 0, 0);

      /* Enable EXTI Interrupt */
      HAL_NVIC_EnableIRQ(OTG_HS_WKUP_IRQn);  
    }
  }


其他的配置和FS一样的了。难道HS配置还有什么特别要注意的地方？
