Fixed documentation typoes and preprocessor checks relating to misspellings of the USE_RAM_DESCRIPTORS token (thanks to Ian Gregg).

Added missing documentation for AUDIO_SAMPLE_FREQUENCY configuration option in the audio device demos.

Fixed CDC demo not sending an empty packet after each transfer to prevent the host from buffering incomming data.

Altered Project and Bootloader makefiles so that the path to the LUFA library can be set in one place.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.

Combined Keyboad and Mouse normal and interrupt driven host demos into unified Keyboard and Mouse host demos.

Ensure that the Keyboard and Mouse demos adhere to the boot protocol specification in that they send a report before the idle period has elapsed if the report data has changed.

Corrections to Keyboard and Mouse combined demos so that all modes (normal, interrupt, fully interrupt) work correctly.

Corrections to Keyboard demo.

Removed AVRISP_Programmer project due to code quality concerns.

Fixed typos in the SPI driver SPI_SPEED_FCPU_DIV_64 and SPI_SPEED_FCPU_DIV_128 masks (thanks to Markus Zocholl).

Corrected CDC class bootloader to fix a few bugs, changed address counter to store x2 addresses for convenience.

Incomplete non-functional BluetoothHost demo removed until it has reached a stable state to prevent confusion.

Added DataflashManager_WriteBlocks_RAM() and DataflashManager_ReadBlocks_RAM() functions to the MassStorage demo, to allow for easy interfacing with a FAT library for dataflash file level access.

Board Dataflash driver now allows for dataflash ICs which use different shifts for setting the current page/byte address (thanks to Kenneth Clubb).

Renamed NO_CLEARSET_FEATURE_REQUEST compile time token to NO_FEATURELESS_CONTROL_ONLY_DEVICE and expanded its function to also remove parts of the Get Status chapter 9 request, to further reduce code usage.

Fixed incorrect/missing control status stage transfers on demos, bootloaders and applications (thanks to Nate Lawson).

Removed SetSystemClockPrescaler() macro, the clock_prescale_set() avr-libc macro has been corrected in recent avr-libc versions

Altered DFU bootloader to use the signature byte constants located in the avr-libc part headers, rather than redefining them in Descriptors.h.

Updated makefiles to reflect new dfu-ee programming target invocations (supplied by Opendous, Inc.).

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.

Changed stream wait timeout counter to be 16-bit, so that very long timeout periods can be set for correct communications with badly designed hosts or devices which greatly exceed the USB specification limits.

Mass Storage Host demo now uses a USB_STREAM_TIMEOUT_MS of two seconds to maintain compatibility with poorly designed devices.

Makefiles and library modified to add a new F_CLOCK constant to give the unprescaled master input clock frequency, so that the correct PLL mask can be determined even when the CPU (F_CPU) clock rate is prescaled outside the normal input range of the PLL.

Started to clean up the AVRISP Programmer project code, donated by Opendous Inc.

USBtoSerial demo now discards all Rx data when not connected to a USB host, rather than buffering characters for transmission next time the device is attached to a host.
