Perform endianness correction in the HID report parser for big-endian platforms.

Replace all calls and references to _delay_ms() in the code with the architecture-agnostic Delay_MS() function.

Improve code generation for the Delay_MS() function on the AVR8 architecture when called with a constant input.

Remove use of avr-libc specific ATOMIC_BLOCK, replace with a new per-architecture set of inline functions to retrieve and manipulate the global interrupt enable bit for each architecture.

Add in documentation for the USB controller common interrupt routine which must be linked to the interrupt controller in the user application on the AVR32 UC3 architecture.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_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.

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.

Fixed Remote Wakeup broken on the AVRs due to the mechanism only operating when the SUSPI bit is set (thanks to Holger Steinhaus).

Remove redundant setting of UIDE in the AVR8 and AVR32 USB controller drivers.

Implemented on-demand PLL clock generation for the U4, U6 and U7 series USB AVRs when automatic PLL mode is specified.

Add support for the inbuilt unique serial numbers in the UC3A3 and UC3A4 models.

Add software FIFOs to the UC3B pipe control interfaces, to match the endpoint control interfaces. Fix incorrect endianness for the Endpoint/Pipe read and write routines.

Porting updates for the UC3B architecture - get UC3B partially enumerating using a modified mouse demo on the EVK1101. Implement a software FIFO for the endpoint banks; datasheet hints that this can be done through hardware as on the AVR8 architecture, but the correct method to do this not discovered yet.

Fixed Still Image Host class driver exiting the descriptor search routine prematurely if the data pipes (but not event pipe) is found.

Fixed missing call to Pipe_SetInfiniteINRequests() in the Pipe_ConfigurePipe() routine.

Add in USB_INT_RegisterHandlers() internal function to register the interrupt handler routines used by LUFA. Add dummy loads after clearing the interrupt lines according to the datasheet.

Add in temporary global interrupts enable/disable macros.

Oops - ensure that only the relevant/available interrupts are defined and used on each architecture.

Make all USB driver headers include USBMode.h first, to ensure that the relevant USB mode macros are defined.

Changed over the AVR8 USB controller interrupt management macros to be inlined functions instead, for better compile-time validity checking and to keep the per-architecture source files as uniform as possible.

Move out common architecture-independent core definitions into the appropriate core dispatch header files.

More AVR32 UC3B architecture ports - USB device mode applications can now be sucessfully compiled, although they will be currently non-functional.

Removed Pipe_ClearErrorFlags(), pipe error flags are now automatically cleared when Pipe_ClearError() is called.

More UC3B architecture porting.

Rename architecture specific driver files, to make them appear with uniquely identifying filenames in the documentation.

Start update of documentation to support possible multiple architectures in the future - alter \file documentation to automatically copy in the module documentation where possible.

Initial restructuring of the core USB driver module to support multiple architectures in the future.
