Updated all host mode demos and projects to use the EVENT_USB_Host_DeviceEnumerationComplete() event callback for device configuration instead of manual host state machine manipulations in the main application task.

Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.

Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.

Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.

Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.

Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Fix inverted LEDs_GetLEDs() result for the EVK1100 and EVK1101 boards.

Fix logic bug in the incomplete Android Accessory Host demo preventing correct detection of an attached Android Accessory Mode device.

Fixed compile error when FIXED_CONTROL_ENDPOINT_SIZE compile time option was disabled, and a USE_*_DESCRIPTORS compile time option was not enabled on the AVR8s.

Add C++ compatibility to some header files currently missing extern "C" linkage.

Add missing project files for the new HIDReportViewer project to upgrade its status to a finished (working) project.

Rename new Audio class driver functions, callbacks and events to ensure that they contain the USB mode (Device or Host) in the function names.

Rename Audio Host Class driver internal descriptor matching routines to be in line with the rest of the class driver function names.

Fix errors in the new Audio Host mode Class Driver, which would have prevented data from being sent or received properly by the device.

Add microphone/square wave generation compile time switch to the Low Level AudioOutput Host demo.

Pipe_BoundEndpointNumber() has been renamed to Pipe_GetBoundEndpointAddress(), and now returns the correct endpoint direction as part of the endpoint address.

Add Audio_GetSetEndpointProperty() function to the Host mode Audio class driver.

Remove warnings in the documentation for the library class drivers about sequential pipe/endpoint allocation, as by default this is no longer as issue (unless ORDERED_EP_CONFIG is specified).

Added new EVENT_Audio_StreamStartStopChange() event to the Audio Device Class driver to detect stream start/stop events.

Remove custom PIDs on the Class Driver Audio device demos and revert back to the original Audio PIDs, as the low level and class driver demo versions are now descriptor compatible once again.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Added new callback to the Audio Class driver to allow for endpoint control manipulations such as data sample rates.

Modified the Class Driver AudioInput and AudioOutput demos to support multiple sample rates.

Fixed KeyboardHost and KeyboardHostWithParser demos displaying incorrect values when numerical keys were pressed.

Fix broken LowLevel audio demo descriptors.

Minor documentation fixes.

Minor documentation cleanups.

Modify the incomplete AudioInputHost demo for mono audio output.

Altered the definition of the USB_Audio_Descriptor_Format_t descriptor so that the user is now responsible for supplying the supported audio sampling rates, to allow for multiple audio interfaces with different numbers of supported rates and/or continuous sample rates.

Added missing Audio class control request definitions.

Added support for the Audio class GET STATUS request so that it is correctly ACKed when sent by the host.

Update MediaController project to remove the Record usage (not often needed) and explicitly declare each usage for maximum clarity.

Add new MediaController project, a simple Media Playback control manipulator (Play/Pause/Next Track/Volume/etc.).
