Update CDC Class Driver character stream functions to use the correct avr-libc return codes for errors and EOF.

Fix pointer arithmetic on void byte buffers by explicitly typecasting the buffer pointers to uint8_t* before altering them.

Added new stream creation function to the CDC Class drivers, to easily make standard streams from CDC Class driver instances.

Make Mass Storage device Class driver accept resets at any time, rather than just after a command block has been processed.

Remove the HID device parser from the boot protocol Keyboard/Mouse demos.

Remove dependancies from the LowLevel demos to the ClassDriver demos, since the use of ClassDriver headers now outputs an error when NO_STREAM_CALLBACKS is used.

Make Low Level host demos use void pointers for the configuration descriptor, to prevent warnings when passed to the altered configuration descriptor parsing routines.

Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.

Descriptor processing routines now pass around void pointers rather than uint8_t pointers, as their destination datatype is know well known -- they are just streams of bytes until they are cast to the correct destination type by DESCRIPTOR_CAST.

Add double banking property to LUFA powered projects in the Projects directory. Add guards to macro parameters to ensure that formulas passed as parameters don't mess up the internal macro structure.

Add optional double-banking support to the Device mode Class Drivers, on a per-endpoint, per-interface level.

Added new Printer Host mode ClassDriver demo.

Added table of supported classes and modes to the main USB Class Driver documentation.

Fixed HID report parser collection paths invalid due to misplaced semicolon in the free path item search loop. Increased the default number of collection paths allowable by the parser.

Add some missing documentation to some of the library demos.

Update DevChapter9.c - use the Endpoint_ClearStatusStage() function where possible to reduce code size and (potentially) allow for centralized status stage timeouts.

Fix Joystick device demo HID descriptors - buttons should be placed outside the Pointer collection.

Add new manual pages detailing the advantages of LUFA over the official Atmel USB AVR stack, and reasons why LUFA should be used over a built-from-scratch USB stack.

Make HID device class driver ignore the previous HID report comparison buffer when the user sets it to NULL, disabling automatic report comparisons. Update HID device class driver documentation giving previous report buffer limitations.

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.

Fix AudioOutput and AudioInput class driver demos' descriptors -- incorrect value was being supplied in the audio descritors field giving the number of discrete audio formats the device supports.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Removed accidental reference to the incomplete MIDI class bootloader in the Bootloader folder makefile.

Make MouseHost and KeyboardHost ClassDriver demos use the HID Class driver's structures for the boot protocol Mouse/Keyboard report data, rather than rolling their own.

Make unfinished device mode applications use the VID/PID reserved for LUFA development devices.

Simplify AudioOutput demos, to reduce the number of cycles needed to process each incomming sample.

Changed Audio Class driver sample read/write functions to be inline, to reduce the number of cycles needed to transfer samples to and from the device (allowing more time for processing and output).

Fixed ClassDriver AudioOutput demo not selecting an audio output mode.

Added pinouts to the AVRISP project for a standard ISP 6 Pin header to make construction of a standard ISP programmer easier.

Added new HID_HOST_BOOT_PROTOCOL_ONLY compile time token to reduce the size of the HID Host Class driver when Report protocol is not needed.

Fixed issue in the HID Host class driver's HID_Host_SendReportByID() routine using the incorrect mode (control/pipe) to send report to the attached device.
