int8_t STORAGE_Init_FS (uint8_t lun)

{ /* USER CODE BEGIN 2 */ printf('STORAGE_Init_FS function!\n'); MX_SDIO_SD_Init(); <== answer my question, now it's working like a charm //BSP_SD_Init(); return (USBD_OK); /* USER CODE END 2 */ }

Still got unexpected error for reading message when I login ???
