Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

Split out endpoint and pipe stream functions into new EndpointStream.c/.h and PipeStream.c/.h files.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Move and rename DevChaper9.c/.h and HostChapter9.c/.h to the HighLevel directory, new named DeviceStandardReq.c/.h and HostStandardReq.c/.h.

Rename LowLevel.c/.h to USBController.c/.h.

Remove dependancies on the complete <avr/io.h> header in the HighLevel USB driver directory, to ensure less work is required in later (possible) ports.

Reduce spacing of the structure elements in StdDescriptors.h to make the code more readable.

Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Better fix to avoid void pointer arithmetic in ConfigDescriptor.h to regain C++ compatibility (thanks to Michael Hennebry).

Remove void* arithmetic in the USB_GetNextDescriptor() static inline function, to make the header file C++ compatible once again. Implement workaround for an obscure GCC bug which can cause incorrect code generation under some circumstances when the void* is re-cast.

Small tweaks to ConfigDescriptor.c/.h to ensure pointers use the correct type, and to remove const attribute from the descriptor comparator callback function pointer type define, and into the function prototype instead.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

Removed two-step endpoint/pipe bank clear and switch sequence for smaller, faster endpoint/pipe code.

Added spacing between multiple paragraphs in Doxygen \note sections.

Removed call to the clock prescaler reset function in the Teensy bootloader to save space - the user application is accessed via a watchdog reset anyway, so the prescale reset would only affect the speed of the bootloader itself.

Remove accidentally duplicated model-specific peripheral driver files.

Fixed compilation error in the AudioInput demos when MICROPHONE_BIASED_TO_HALF_RAIL is defined (thanks to C. Scott Ananian).

Minor documentation cleanups.

Make sure HID class driver uses properly cast pointers when writing to the report buffer.

Add more include protection macros to give the user warnings when they try to manually include private driver header files, instead of the public driver headers.

Fixed incorrect values of USB_CONFIG_ATTR_SELFPOWERED and USB_CONFIG_ATTR_REMOTEWAKEUP tokens (thanks to Claus Christensen).

Mark the AVRISP-MKII project descriptors as being both Bus Powered and Device Powered.

Copy over file level documentation of the peripheral drivers to the module level documentation.

Clean up and add more comments to the AVRISP-MKII project. Make sure the SPI_MULTI command handler supports multiple packet responses. Use slightly smaller/faster repeated indirect-load commands when retrieving the PDI target's memory CRCs.

Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).

Added CDC_Host_Flush() function to the CDC Host Class driver to flush sent data to the attached device.

Simplified the USB.h master include file's target validity checks.
