STM32H743 usb初始化失败不知道是什么原因

使用rtt3.1.4版本，驱动是最新的，usb初始化HAL_PCD_Init(pcd);失败，跟进去发现在USB_CoreReset(USB_OTG_GlobalTypeDef *USBx)超时，

/* Core Soft Reset */
count = 0U;
USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST;
do
{
if (++count > 200000U)
{
return HAL_TIMEOUT;
}
}
while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST);

进入了rerun HAL_TIMEOUT 。在F407运行时正常的，不知道是什么原因。

H7使用了一下时钟配置

大神们，帮忙检阅一下
