* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
* - Altered the Mass Storage Host class driver so that SCSI data STALLs from the attached device can be recovered from automatically without
* having to reset the Mass Storage interface
* - USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors)
+ * - Reordered board name definition indexes so that a mispelled BOARD compile option will default to BOARD_USER rather than BOARD_USBKEY
* - Library Applications:
* - Altered the Mass Storage Host LowLevel demo so that SCSI data STALLs from the attached device can be recovered from automatically without
* having to reset the Mass Storage interface
