Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.

Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.

Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning, no need to call Dataflash_ToggleSelectedChipCS() afterwards.

Added new DATAFLASH_CHIP_MASK() macro to the Dataflash driver, which returns the Dataflash select mask for the given chip index.

Updated MassStorage device block write routines to use ping-pong Dataflash buffering to increase throughput by around 30%.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).

Fixed MassStorage demo not clearing the reset flag when a Mass Storage Reset is issued while not processing a command.

Added new USE_INTERNAL_SERIAL define for using the unique serial numbers in some AVR models as the USB device's serial number, added NO_INTERNAL_SERIAL compile time option to turn off new serial number reading code. Updated Mass Storage and CDC based demos to use the new device serial number if the device it is compiled for supports it.

Added USE_INTERNAL_SERIAL compile time option to automatically read out the internal unique serial number as the device's serial number descriptor on supported AVR models.

Fix makefiles -- the auto-addition of -D switches to each LUFA compile time option was faulty, due to GNUMake becomming confused by the spaces in the USE_STATIC_OPTIONS lines. Make user add in the switches explicitly instead.

Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.

Better documentation for the MissleLauncher project - add credit to PyLauncher project.

Change MIDI demos to use real MIDI command values, and shift for the USB wrapper, rather than shift for the MIDI bytes. This is a little confusing for the MIDI USB wrapper, but allows for the use of real standardized MIDI command values.

Split out common defines/types from class drivers into a seperate common class driver directory.

Make central USB Class driver dispatch headers, used for both device and host modes.

Changed per-device controller preprocessor checks over to per-device series for better device control.

Fixed error in Endpoint.c using HSOFI rather than SOFI for counting elapsed milliseconds.

Changed to new device mode Class Driver function name prefixes to make way for similar host mode Class drivers.

Fixes to the MIDI device demos (ClassDriver, LowLevel); discard unused read-in events from the host, use standard MIDI event structure in low level demo rather than sending individual bytes.

MIDI device demo no longer blocks if a note change event is sent while the endpoint is not ready.

Copy and convert incomplete Bluetooth Host demo to the library.

Remove outdated AVRStudio project files from demos, projects, bootloaders. Fix makefiles of ClassDriver device demos.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.

Added multiple Report ID support to the HID class driver. Removed OUT endpoint support from HID driver (all OUT reports are now processed through control requests) as a seperate endpoint had issues with determining the exact output report length.

Ensure all USB device class drivers have the same three main functions as their interface for consistency.

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 new Start of Frame event from the library; performance suffered far too much and it was only useful in one of the standard classes (HID). Altered HID demos to use the previous method of tracking millisecond periods via a hardware timer rather than the SOF events.

Fixed MIDI class driver blocking on unread events to the host.

Add MIDI class driver, update MIDI device demo to use the new USB class driver. All device demos/projects have now been converted to the new library class drivers, although documentation is yet to be completed.

Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet.

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.

Change USBtoSerial Tx to polling-driven rather than interrupt driven, to ensure more time for the Rx interrupt to be serviced.

Moved out each demos' functionality library files (e.g. Ring Buffer library) to /Lib directories for a better directory structure.

Deleted StdDescriptors.c, renamed USB_GetDescriptor() to CALLBACK_USB_GetDescriptor, moved ConfigDescriptor.c/.h from the LUFA/Drivers/USB/Class/ directory to LUFA/Drivers/USB/HighLevel/ in preperation for the new USB class APIs.
