Added new USB_Host_GetDeviceDescriptor() convenience function to retrieve the attached device's Device descriptor.
Make Pipe_ConfigurePipe() mask the given endpoint number against PIPE_EPNUM_MASK to ensure the endpoint IN direction bit is cleared to prevent endpoint type corruption.
Fix documentation mentioning Pipe_GetCurrentToken() function when real name is Pipe_GetPipeToken().
Redocumented all device demos, now that they have changed over to the new USB class drivers.
Added C linkage to class drivers for C++ support.
Added prefixes to most of the class driver constants to prevent name clashes.
Removed scheduler and memory allocation libraries.
Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).
Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.
Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley).
Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code.
Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code.
Further documentation improvements - removed file view from the main library documentation, replaced file references in the documentation with group references.
The USB_UnhandledControlPacket event has had its parameters removed, in favour of accessing the new USB_ControlRequest structure.
The Endpoint control stream functions now correctly send a ZLP to the host when less data than requested is sent.
Removed Endpoint_ClearCurrentBank() and Pipe_ClearCurrentBank() in favour of new Endpoint_ClearIN(), Endpoint_ClearOUT(), Endpoint_ClearControlIN(), Endpoint_ClearControlOUT(), Pipe_ClearIN(), Pipe_ClearOUT(), Pipe_ClearControlIN() and Pipe_ClearControlOUT() macros (done to allow for the detection of packets of zero length).
Renamed *_ReadWriteAllowed() macros to *_IsReadWriteAllowed() to remain consistent with the rest of the LUFA API.
Endpoint_IsSetupReceived() macro has been renamed to Endpoint_IsSETUPReceived(), Endpoint_ClearSetupReceived() macro has been renamed to Endpoint_ClearControlSETUP(), the Pipe_IsSetupSent() macro has been renamed to Pipe_IsSETUPSent() and the Pipe_ClearSetupSent() macro is no longer applicable and should be removed - changes made to compliment the new endpoint and pipe bank management API.
Updated all demos, bootloaders and projects to use the new endpoint and pipe management APIs (thanks to Roman Thiel).
Updated library doxygen documentation, added groups, changed documentation macro functions to real functions for clarity.
Removed old endpoint and pipe aliased read/write/discard routines which did not have an explicit endian specifier for clarity.
Removed the ButtLoadTag.h header file, as no one used for its intended purpose anyway.
Renamed the ATTR_ALWAYSINLINE function attribute macro to ATTR_ALWAYS_INLINE to match the style of the other function attribute macro names.
Added ATTR_ALWAYS_INLINE attribute to several inlined library functions, to ensure they are inlined in all circumstances.
Cleanups to Endpoint.h and Pipe.h. Added better documentation for the endpoint and pipe interrupts.
