  USB Host Mass Storage Class SCSI Interface Driver (Header File)

Description:
    This is the header file for a USB Embedded Host that is using a SCSI
    interface to the Mass Storage Class.

    This file provides the interface between the file system and the USB Host
    Mass Storage class.  It translates the file system funtionality requirements
    to the appropriate SCSI commands, and sends the SCSI commands via the USB
    Mass Storage class.  This header file should be included with usb_host.h and
    usb_host_msd.h to provide the USB Mass Storage Class interface.  It must
    be included after the application-specific usb_config.h file, the USB Host
    header file usb_host.h, and the USB Host MSD header file usb_host_msd.h,
    as definitions in those files are required for proper compilation.

    The functions in this file are designed to interface the Microchip Memory
    Disk Drive File System library (see Application Note AN1045) to the USB
    Host Mass Storage Class, allowing a PIC application to utilize mass storage
    devices such as USB flash drives.  For ease of integration, this file
    contains macros to allow the File System code to reference the functions in
    this file.

    Currently, the file system layer above this interface layer is limited to
    one LUN (Logical Unit Number) on a single mass storage device.  This layer
    accepts and stores the max LUN from the USB MSD layer, but all sector reads
    and writes are hard-coded to LUN 0, since the layer above does not specify
    a LUN in the sector read and write commands.  Also, to interface with the
    existing file system code, only one attached device is allowed.

Summary:
    This is the header file for a USB Embedded Host that is using a SCSI
    interface to the Mass Storage Class.
