Update XMEGA board drivers to use the port inversion feature of the XMEGA architecture rather than performing the inversion in software. Add partially completed XMEGA-B1-XPLAINED Dataflash board driver and revert implementation of the XMEGA-A3BU-XPLAINED Dataflash driver as the chip is connected to the USART, not the SPI interface.

Make an explicit constant name for the CMDEX bit of the target's NVM command register in the AVRISP-MKII Clone project.

Allow serial strings to be generated on the older AVR8 devices which do not explicitly state they contain unique values in the datasheet, as this appears to be implemented in hardware.

Updated the AVRISP-MKII Clone programmer project to be compatible with the latest version of AVR Studio (version 5.1).

Changed the AVRISP-MKII Clone programmer project to report a fixed 3.3V VTARGET voltage on USB AVRs lacking an ADC instead of 5V to prevent warnings in AVR Studio 5.1 when programming XMEGA devices.

Fix Dataflash driver for the A3BU-Xplained board.

Minor documentation improvements.

Add (still preliminary) support for the ATXMEGA64A4 and ATXMEGA128A4. Fix minor error in the AVRISP-MKII clone project descriptors.

Update LUFAConfig.h with the new compile time options, re-format Doxygen documentation for all compile time options.

Added INVERTED_VBUS_ENABLE_LINE and NO_AUTO_VBUS_MANAGEMENT compile time options (thanks to Opendous Inc.).

Fixed invalid PID value used in the TempDataLogger project host application (thanks to Anupam Pathak).

Add API support signature to the CDC and DFU class bootloaders, so that the application can detect the bootloader's API support.

Fix errors in the new Micropendous board drivers. Reorder the board definition macro indexes so that misspelled board names default to BOARD_USER rather then BOARD_USBKEY.

Fixed AVRISP-MKII Clone timing out on long programming commands such as programming the EEPROM on an ATMEGA8 (thanks to Martin Kelling).

Add missing reference to the BootloaderAPI.S source file in the DFU and CDC class bootloader AVRStudio 4 project files.

Fixed DFU class bootloader not resetting the LED pins as high impedance inputs when a software jump to the user applications is requested.

Added new LEDs_Disable(), Buttons_Disable() and Joystick_Disable() functions to the board hardware drivers.

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

Make all AVRISP-MKII programmer parameters readable, since there's no real good reason to restrict parameter reads. Fix misspelt target reset polarity EEPROM variable.

Minor bootloader tweaks; make some functions static where possible to reduce the compiled binary size, add additional comments to the makefiles.

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

Fixed incorrect implementation of LEDs_ToggleLEDs() for the Adafruit-U4 board (thanks to Caroline Saliman).

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

Don't validate the Device Descriptor's vendor ID when validating that a device is an Android Accessory device; the Product ID and (later) Accessory protocol support is enough to probe AOA class support without having to maintain a list of Android device manufacture VID values.

Change PIPE_PIPENUM_MASK from 0x07 to the more generic 0x0F to allow for full pipe address support in USB host architectures other than the current AVR8 devices. Minor documentation improvements.

Altered the Mass Storage Host class driver so that SCSI data STALLs from the attached device can be recovered from automatically without having to reset the Mass Storage interface.

Altered the Mass Storage Host LowLevel demo so that SCSI data STALLs from the attached device can be recovered from automatically without having to reset the Mass Storage interface.
