While using USB Mass Storage Device and SD Card , at a time only One Device is detecting

[Abin]

Hai All,

I am working on STM32F205VET and I have enabled USB Mass storage, SD Card and FATFS. I need to use SD card and USB mass Storage at a time, that means need to access the files.But I found that based on the 

FATFS_LinkDriver preference makes that one device in Disable mode. I am giving the Initialization function here.

 

void MX_FATFS_Init(void)

{

 

  /*## FatFS: Link the USER driver ###########################*/

 

retUSER = FATFS_LinkDriver(&USER_Driver, USERPath);

 

  /*## FatFS: Link the USBH driver ###########################*/

 

 

     retUSBH = FATFS_LinkDriver(&USBH_Driver, USERPath);

 

 

  /* USER CODE BEGIN Init */

     /*Use the first link driver for SD card and second for USB*/

  /* additional user code for init */

  /* USER CODE END Init */

}

 

Can yo
