Fixed GenericHID demo not starting USB and HID management tasks when not using interrupt driven modes (thanks to Carl Kjeldsen).

Added support to the CDCHost demo for devices with mutiple CDC interfaces which are not the correct ACM type preceeding the desired ACM CDC interface.

Added preprocessor checks and documentation to the bootloaders giving information about missing SIGNATURE_x defines due to outdated avr-libc versions.

Add call to MassStore_WaitForDataReceived() in MassStore_GetReturnedStatus() to ensure that the CSW has been received in the extended MSC timeout period before continuing, to prevent long processing delays from causing the MassStore_GetReturnedStatus() to early-abort.

All comments in the library, bootloaders, demos and projects have now been spell-checked and spelling mistakes/typos corrected.

Changed GenericHID device demo to use the LUFA scheduler, added INTERRUPT_DATA_ENDPOINT and INTERRUPT_CONTROL_ENDPOINT compile time options.

Corrections to the KeyboardHost and MouseHost demos' pipe handling to freeze and unfreeze the data pipes at the point of use.

Fixed Still Image Host SImage_SendData() function not clearing the pipe bank after sending data.

Corrected bitfields -- the smallest datatype required for each bitfield is now used, rather than relying on GCC to truncate unused bytes in bitfields (thanks to Walt Sacuta).

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.

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.

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

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.
