问题描述：
使用stm32cubemx生成的sdio和usb Mass Storage Class的代码后，在USB_DEVICE\App\usbd_storage_if.c文件里面的接口调用以下函数出现卡死问题：
SD_Driver.disk_initialize(0);
SD_Driver.disk_read(lun, buf, blk_addr, blk_len)
SD_Driver.disk_write(lun, buf, blk_addr, blk_len);

解决办法:
1、STORAGE_Init_FS里面不直接调用disk_initialize，在MX_SDIO_SD_Init里面直接初始化sd卡，

2、读写sd卡的函数改为dma的读写接口：
HAL_SD_ReadBlocks_DMA(&hsd, buf, blk_addr, blk_len)
HAL_SD_WriteBlocks_DMA(&hsd, buf, blk_addr, blk_len)


USB_DEVICE\App\usbd_storage_if.c文件的具体代码如下：
