Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Remove dfu-programmer program switches, to ensure maximum compatibility with all dfu-programmer versions.

Added the --suppress-bootloader-mem option to the makefile dfu target, to ensure that writes to the bootloader section of the AVR's flash memory are ignored (thanks to Axel Rohde).

Fixed incorrect command name for EEPROM memory programming in the makefile dfu-ee target.

Makefile whitespace fixes.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

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).

Moved calls to Device mode Class Driver events to after the request has been acknowledged, so that long event handlers do do skew the timing of the control requests.


Fixed USBtoSerial and Benito project SetLineEncoding calls failing if the USART is busy, due to the RX ISR delaying the control request handler.

Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code.

Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.

Fix invocations of avr-size in all makefiles broken on unpatched *nix systems, due to the recent update to the latest WinAVR makefile template.

Fix XPLAINBridge project discarding characters from the USB interface due to a double read from the endpoint.

Make XPLAINBridge and USBtoSerial projects more reliable by forcing a flush if the UART-to-USB buffer becomes nearly full.

Reduce locking in the LightweightRingBuffer.h header files by only locking on the update of the buffer count, and require insertions and removals from each buffer to occur in only one execution thread.

Fix CDC_*_ReceiveByte() returning 0 when the interface is not configured, instead of the new -1 error value.

Fix CDC_Host_ReceiveByte() not re-freezing the pipe if no packet has been received.

Remove redundant Pipe token set commands in the CDC and RNDIS host class drivers.

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

Altered the CDC Deivice and Host Class drivers' receive byte routines, so that no data is indicated by a negative return value.

Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer.

Oops - need to turn off USART via control register B before reconfiguring, fix ordering of USART control register modifications in the Benito and USBtoSerial projects.

Fixed Benito and USBtoSerial projects not turning off the USART before reconfiguring it, which could cause incorrect operation to occur (thanks to Bob Paddock).

Added periodic flush timer to the Benito project. Alter the serial transmission code so that sent bytes do not block the remainder of the main program code from running.

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

Disable strict aliasing explicitly in the project makefiles, as this is apparently enabled by default in newer AVR-GCC builds, and aliasing is used heavily for type-punning through the LUFA and third party library's codebase.

Removed the automated checking of event names in the demo, project and bootloader makefiles due to inconsistancies between the behaviour of the command line tools used to perform the check on each platform.

Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.

Alter the ring buffer library headers to have both atomic and non-atomic insertion/removal routines. Modify the existing projects so that buffer operations performed in an ISR use the shorted non-atomic versions, as they are already performed in a blocking ISR.

Alter USBtoSerial demo so that it does not enter a blocking loop to send data from the USB to the USART, as this can cause dropped bytes in the reception code if large amounts of data are sent in both directions at the same time. Added a flush timer to the USBtoSerial code for the USART to USB interface, so that multiple bytes can be sent in the same USB packet.

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Maximise the size of the ring buffers in the Benito/XPLAINBridge/USBtoSerial projects, so that they should never become full under normal conditions.

Oops - light weight ring buffer documentation used \ref instead of \param to document function parameters.

Add the svn:eol-style property onto new files which where missing it to ensure uniform line endings.

Replace ring buffer library in Benito and USBtoSerial projects with the new lightweight ring buffer header to improve reliability.

Renamed CDC device class demos' ManagementEndpoint descriptor to NotificationEndpoint to more accurately indicate its purpose.

Fixed AVRISP-MKII clone project not correctly issuing SET EXTENDED ADDRESS commands when the extended address boundary is crossed during programming or readback (thanks to Gerard Sexton).

Fixed warnings when building the AVRISP-MKII clone project with the ENABLE_XPROG_PROTOCOL compile time option disabled.
