/** \mainpage Mass Storage Device Demo
*
* \section Sec_Compat Demo Compatibility:
*
* The following list indicates what microcontrollers are compatible with this demo.
*
* \li Series 7 USB AVRs (AT90USBxxx7)
* \li Series 6 USB AVRs (AT90USBxxx6)
* \li Series 4 USB AVRs (ATMEGAxxU4)
* \li Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
*
* \section Sec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this demo.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>
* </tr>
* <tr>
* <td><b>USB Class:</b></td>
* <td>Mass Storage Device</td>
* </tr>
* <tr>
* <td><b>USB Subclass:</b></td>
* <td>Bulk-Only Transport</td>
* </tr>
* <tr>
* <td><b>Relevant Standards:</b></td>
* <td>USBIF Mass Storage Standard \n
* USB Bulk-Only Transport Standard \n
* SCSI Primary Commands Specification \n
* SCSI Block Commands Specification</td>
* </tr>
* <tr>
* <td><b>Supported USB Speeds:</b></td>
* <td>Full Speed Mode</td>
* </tr>
* </table>
*
* \section Sec_Description Project Description:
*
* Mass Storage device demonstration application. This gives a simple
* reference application for implementing a USB Mass Storage device using
* the basic USB UFI drivers in all modern OSes (i.e. no special drivers
* required).
*
* On start-up the system will automatically enumerate and function as an
* external mass storage device which may be formatted and used in the same
* manner as commercial USB Mass Storage devices.
*
* You will need to format the mass storage drive upon first run of this
* demonstration - as the device acts only as a data block transport between
* the host and the storage media, it does not matter what file system is used,
* as the data interpretation is performed by the host and not the USB device.
*
* This demo is not restricted to only a single LUN (logical disk); by changing
* the TOTAL_LUNS value in DataflashManager.h, any number of LUNs can be used
* (from 1 to 255), with each LUN being allocated an equal portion of the available
* Dataflash memory.
*
* The USB control endpoint is managed entirely by the library using endpoint
* interrupts, as the INTERRUPT_CONTROL_ENDPOINT option is enabled. This allows for
* the host to reset the Mass Storage device state during long transfers without
* the need for complicated polling logic.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td><b>Define Name:</b></td>
* <td><b>Location:</b></td>
* <td><b>Description:</b></td>
* </tr>
* <tr>
* <td>TOTAL_LUNS</td>
* <td>AppConfig.h</td>
* <td>Total number of Logical Units (drives) in the device. The total device capacity is shared equally between each drive -
* this can be set to any positive non-zero amount.</td>
* </tr>
* <tr>
* <td>DISK_READ_ONLY</td>
* <td>AppConfig.h</td>
* <td>Configuration define, indicating if the disk should be write protected or not.</td>
* </tr>
* </table>
