* - Added new CALLBACK_Audio_Device_GetSetInterfaceProperty() callback to the Audio Device Class driver
* - Added new LEDs_Disable(), Buttons_Disable() and Joystick_Disable() functions to the board hardware drivers
* - Added support for the Micropendous family of boards
+ * - Added INVERTED_VBUS_ENABLE_LINE and NO_AUTO_VBUS_MANAGEMENT compile time options (thanks to Opendous Inc.)
* - Library Applications:
* - Added User Application APIs to the CDC and DFU class bootloaders
* - Added INVERTED_ISP_MISO compile time option to the AVRISP-MKII clone project (thanks to Chuck Rohs)
* the compile time token may be defined in the application's makefile to disable automatic flushing during calls to the class driver USB
* management tasks.
*
+ *
* \section Sec_SummaryUSBTokens General USB Driver Related Tokens
* This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.
*
* the ability to receive USB Start of Frame events via the \ref EVENT_USB_Device_StartOfFrame() or \ref EVENT_USB_Host_StartOfFrame() events is removed,
* reducing the compiled program's binary size.
*
+ *
* \section Sec_SummaryUSBDeviceTokens USB Device Mode Driver Related Tokens
* This section describes compile tokens which affect USB driver stack of the LUFA library when used in Device mode.
*
* they will fail to enumerate correctly. By placing a delay before the enumeration process, it can be ensured that the bus has settled
* back to a known idle state before communications occur with the device. This token may be defined to a 16-bit value to set the device
* settle period, specified in milliseconds. If not defined, the default value specified in Host.h is used instead.
+ *
+ * <b>INVERTED_VBUS_ENABLE_LINE</b> - (\ref Group_Host) - <i>All Architectures</i>
+ * If enabled, this will indicate that the USB target VBUS line polarity is inverted; i.e. it should be pulled low to enable VBUS to the
+ * target, and pulled high to stop the target VBUS generation.
+ *
+ * \note On AVR8 architecture devices, this compile time option requires \c NO_AUTO_VBUS_MANAGEMENT to be set.
+ *
+ * <b>NO_AUTO_VBUS_MANAGEMENT</b> - (\ref Group_Host) - <i>All Architectures</i>
+ * Disables the automatic management of VBUS to the target, i.e. automatic shut down in the even of an overcurrent situation. When enabled, VBUS
+ * is enabled while the USB controller is initialized in USB Host mode.
