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.

Tighten up the implementations of the USB_Device_SetDeviceAddress(), USB_Controller_Reset() and USB_PLL_On() functions for the AVR8 devices.

Minor corrections to the documentation of the USB_Control_Request_t enum.

Slight improvements to the ADC peripheral driver example in the manual.

Fix HID_Host_SetIdlePeriod() function to send the correct request type to the device, remove reference to unavailable (and not needed) local variable.

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

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.

Make the HID Report Parser Get/Set Report Item routines fail if a NULL pointer to a report item is given.

Minor visual enhancement to the HIDReportViewer project.

Code style fixes for the Device mode USB Audio Class driver to make it more in line with the style of the other library Device Class drivers.

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

Add macro guards to the templated C files to prevent compile errors if they are mistakenly compiled as regular source files in a LUFA project.

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

Ensure that only the requested Audio class pipes are mapped to endpoints within the device for a specific Audio Host Class driver instance.

Fix const-correctness of the Audio Host Class driver.

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.

Partial commit: Rename USBFOO LED driver to fix capitalisation of file name, which will cause issues on *nix systems.

Partial commit: Rename USBFOO LED driver to fix capitalisation of file name, which will cause issues on *nix systems.

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.
