STM32F746 USB MSC Host not working

I am using STM32F746G-DISCO board.

Configured USB FS in MSC HOST mode.

After connecting the Pendrive, ReqStatus in following part returns USBH_BUSY

  case ENUM_IDLE:

   /* Get Device Desc for only 1st 8 bytes : To get EP0 MaxPacketSize */

   ReqStatus = USBH_Get_DevDesc(phost, 8U);
