  49  *
  50  *  Dual LUN Mass Storage demonstration application. This gives a simple
  51  *  reference application for implementing a multiple LUN USB Mass Storage
  52  *  device using the basic USB UFI drivers in all modern OSes (i.e. no
  53  *  special drivers required).
  54  *
  55  *  On start-up the system will automatically enumerate and function as an
  56  *  external mass storage device with two LUNs (separate disks) which may
  57  *  be formatted and used in the same manner as commercial USB Mass Storage
  58  *  devices.
  59  *
  60  *  You will need to format the mass storage drives upon first run of this
  61  *  demonstration - as the device acts only as a data block transport between
  62  *  the host and the storage media, it does not matter what file system is used,
  63  *  as the data interpretation is performed by the host and not the USB device.
  64  *
  65  *  This demo is not restricted to only two LUNs; by changing the TOTAL_LUNS
  66  *  value in MassStorageDualLUN.h, any number of LUNs can be used (from 1 to
  67  *  255), with each LUN being allocated an equal portion of the available
  68  *  Dataflash memory.
  69  *
  70  *  The USB control endpoint is managed entirely by the library using endpoint
  71  *  interrupts, as the INTERRUPT_CONTROL_ENDPOINT option is enabled. This allows for
  72  *  the host to reset the Mass Storage device state during long transfers without
  73  *  the need for complicated polling logic.
  74  *

  87  *    <td>MassStorage.h</td>
  88  *    <td>Total number of Logical Units (drives) in the device. The total device capacity is shared equally between each drive -
  89  *        this can be set to any positive non-zero amount.</td>
