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.
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.
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.
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.
Minor code cleanups to add const and reformat where missing, as well as abstract out the internal device signature start address into a macro, so that it can be altered to suit particular devices within a single architecture if needed.
Add missing documentation to the USB_Device_States_t enum.
Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.
Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.
Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions.
Altered the serial byte receive function to make it non-blocking.
Fix reversed byte ordering of multi-byte HID data.
Added support to the HID parser for extended USAGE items that contain the usage page as well as the usage index.
Removed the HID_IOF_NON_VOLATILE and HID_IOF_VOLATILE flags from HID INPUT items where the flag is invalid. Changed over HID OUTPUT items to use HID_IOF_NON_VOLATILE.
Change over MagStripe project to use HID_DESCRIPTOR_KEYBOARD() for its HID report. Change over MouseHostDevice demo to use HID_DESCRIPTOR_MOUSE() for its HID report.
Fixed ReportID not being removed from the feature/out report data array in the HID class driver when Report IDs are used.
Added new MAX() and MIN() convenience macros.
Changed over all project and demo HID report descriptors to use the new HID report item macros.
Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.
Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.
Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.
Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).
