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.).

Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.

Fix TeensyHID bootloader not properly shutting down the USB interface to trigger a disconnection on the host before resetting the AVR.

Fixed Mass Storage Host Class driver and Low Level demo not clearing the error condition if an attached device returns a STALL to a GET MAX LUN request (thanks to Martin Luxen).

Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.

Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.

Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.

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

Better checking of whether a packet is received in the RNDISEthernetHost Class driver demo - show busy LED status while packets are being printed out.

Make the RNDISEthernetHost Class driver demo print out incomming packets from the attached RNDIS device.

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new RNDISHost Host LowLevel demo. Fixed misnamed Pipe_SetPipeToken() macro for setting a pipe's direction. Fixed CDCHost failing on devices with bidirectional endpoints.

Make the StandaloneProgrammer project seamlessly read out drive contents from either an attached FAT formatted drive when in host mode, or the onboard FAT formatted dataflash when in device mode.

Fixed incorrect values for REPORT_ITEM_TYPE_* enum values causing corrupt data in the HID Host Parser.

Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint.

Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos.

Add new (incomplete) StandaloneProgrammer project, using the ELM Petite FAT library to read files stored on the board's dataflash by the host.

Change device demos which use the joystick to use the natural UP, DOWN, LEFT, RIGHT ordering in all demos when checking the joystick's position.

Corrected the name of the misnamed USB_GetDeviceConfigDescriptor() function to USB_Host_GetDeviceConfigDescriptor().

Extend incomplete RNDISHost demo -- can not enumerate a RNDIS device correctly and set the packet filter. No packets are received yet from the test device, need to investigate additional SET commands to see if any critical OIDs have been missed.

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.

Added new Printer Host mode ClassDriver demo.

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

Add some missing documentation to some of the library demos.

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.
