STM32CUBEIDE USB Slave 读取SD卡

使用STM32CUBEIDE软件，生成USB Slave 读取SD卡，直接用该软件烧录到STM32F407中，可以实现热插拔功能。有些细节要注意：
第一，基于HAL库，对于SDIO时钟的配置，貌似不能0分频（否则SD卡读写文件错误，也无法识别SD卡），必须2分频，代码如下：

第二，修改usbd_storage_if.c文件，这里好多需要用户自定义，代码 usbd_storage_if.c 更改如下：

我这里没有使用高速USB，只是普通的USB，速度最高只能达到 355KB/秒，而且很稳定，但是没有达到预期的1MKB/秒，测试发现与SDIO时钟分频有关，但是无法提速上去，贴友有没有办法提速上去？？？
