Added new CALLBACK_Audio_Device_GetSetInterfaceProperty() callback to the Audio Device Class driver.

USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Update AudioInput and AudioOutput Class Driver device mode demos to use a switch statement when selecting the audio request type for clarity.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

Rename new Audio class driver functions, callbacks and events to ensure that they contain the USB mode (Device or Host) in the function names.

Correct errors in the existing Audio demo description files due to the new demo features (variable sampling rate vs. a fixed sampling rate).

Fix errors in the new Audio Host mode Class Driver, which would have prevented data from being sent or received properly by the device.

Add microphone/square wave generation compile time switch to the Low Level AudioOutput Host demo.

Remove custom PIDs on the Class Driver Audio device demos and revert back to the original Audio PIDs, as the low level and class driver demo versions are now descriptor compatible once again.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Added new callback to the Audio Class driver to allow for endpoint control manipulations such as data sample rates.

Modified the Class Driver AudioInput and AudioOutput demos to support multiple sample rates.

Fixed KeyboardHost and KeyboardHostWithParser demos displaying incorrect values when numerical keys were pressed.

Fix broken LowLevel audio demo descriptors.

Minor documentation fixes.

Altered the definition of the USB_Audio_Descriptor_Format_t descriptor so that the user is now responsible for supplying the supported audio sampling rates, to allow for multiple audio interfaces with different numbers of supported rates and/or continuous sample rates.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Add const to all project descriptor definitions for safety.

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Fixed incorrect PollingIntervalMS values in the demo/project/bootloader endpoint descriptors (thanks to MCS Electronics).

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

Renamed the EVENT_USB_Device_UnhandledControlRequest() event to EVENT_USB_Device_ControlRequest() as it is now fired before the library request handlers, not afterwards.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.
