RTTHREAD USBHOST的使用问题，一直不能找出设备描述符等

用的RTTHREAD1.10
USBHOST现在用的文件：
1 RT-Thread 1.1.0componentsdriversusbusbhost里所有文件
2 ART_work-0094hardwareARTplatformdrivers 里stm32f4xx_hcd.c usb_bsp.c usb_conf.h usbh_conf.h
3 官方库里的文件 usbh_hcs.c usbh_ioreq.c usb_core.c usb_hcd.c usb_hcd_int.c

在applications.c  里添加
```static void rt_init_thread_entry(void* parameter)
{
/* 组件初始化 */
#ifdef RT_USING_COMPONENTS_INIT
    rt_components_init();
#endif
/* 注册设备 */
#ifdef RT_USING_USB_HOST
    /* register stm32 usb host controller driver */
    rt_hw_susb_init();
#endif
	
}```
components.c里添加
```void rt_components_init(void)
{
/* 组件初始化 */
#ifdef RT_USING_FINSH
    /* initialize finsh */
    finsh_system_init();
    finsh_set_device(RT_CONSOLE_DEVICE_NAME);
#endif

#ifdef RT_USING_USB_HOST
	rt_usb_host_init();
#endif
	
    return;
}```
startup.c文件里这个没动
```void rtthread_startup(void)
{
	/* initialize board */
	rt_hw_board_init();

/* show version */
	rt_show_version();

#ifdef RT_USING_HEAP
    rt_system_heap_init((void*)STM32_SRAM_BEGIN, (void*)STM32_SRAM_END);
#endif

/* initialize scheduler system */
	rt_system_scheduler_init();

/* initialize application */
	rt_application_init();

/* initialize timer thread */
    rt_system_timer_thread_init();
	/* initialize idle thread */
	rt_thread_idle_init();

/* start scheduler */
	rt_system_scheduler_start();

/* never reach here */
	return ;
}```

改usb_bsp.c配置为stm32f4discovery板使用
现在下载进板USBHOST那个电源灯不亮，但串口调试工具用list_device()有显示susb
把rt_device_init_all();添加到rt_init_thread_entry()里USBHOST电源灯亮，但程序不进USB枚举

是不是还漏了什么文件还是哪里初使化没写好？
