+  *  - Core:

+  *   - Android Accessory Host property strings changed from a struct of pointer to an array to prevent unaligned access on greater than 8-bit architectures

+  *   - Audio Device Class driver changed to also require the index of the Audio Control interface within the device, for SET/GET/CUR/MIN/MAX/RES property adjustments

+  *   - Removed variable axis support from the HID_DESCRIPTOR_JOYSTICK() macro due to OS incompatibilities, replaced with fixed 3-axis joystick report structure

+  *   - Endpoint indexes are now specified as full endpoint addresses within the device in device mode, rather than a logical index

+  *   - The Endpoint_ConfigureEndpoint() function no longer takes an endpoint direction as a parameter, as this is now deduced from the specified full endpoint

+  *     address and type

+  *      with basic code

+  *    - 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)

+  *      does not exist on these chips (thanks to Marco)

+  *    - Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data

+  *      missed SCSI sense values when the host retrieves the sense key (thanks to Martin Degelsegger)

+  *    - Fixed USBtoSerial and Benito project SetLineEncoding calls failing if the USART is busy, due to the RX ISR delaying the control

+  *  - Fixed USB to Serial demo - class value in the descriptors was incorrect

+  *  - Control endpoint size changed from 64 bytes to 8 bytes to save on USB FIFO RAM and to allow low

+  *    speed mode devices to enumerate properly

+  *  - USB to Serial demo data endpoints changed to dual-banked 16 byte to allow the demo to work

+  *    on USB AVRs with limited USB FIFO RAM

+  *  - Changed demo endpoint numbers to use endpoints 3 and 4 for double banking, to allow limited

+  *    USB device controller AVRs (AT90USB162, AT90USB82) to function correctly

+  *  - Updated Audio Out demo to use timer 1 for AVRs lacking a timer 3 for the PWM output

+  *  - Fixed incorrect USB_DEV_OPT_HIGHSPEED entry in the Mass Storage device demo makefile

+  *  - Optimized Mass Storage demo for a little extra transfer speed

+  *  - Added LED indicators to the Keyboard demo for Caps Lock, Num Lock and Scroll Lock

+  *  - Added Endpoint_Read_Stream, Endpoint_Write_Stream, Pipe_Read_Stream and Pipe_Write_Stream functions

+  *    (including Big and Little Endian variants)

+  *  - Made Dataflash functions inline for speed, removed now empty Dataflash.c driver file

+  *  - Added new SetSystemClockPrescaler() macro (thanks to Joerg Wunsch)

+  *  - Fixed Endpoint_ClearStall() to function correctly on full USB controller AVRs (AT90USBXXX6/7)

+  *  - Endpoint_Setup_In_Clear() and Endpoint_Setup_Out_Clear() no longer set FIFOCON, in line with the

+  *    directives in the datasheet

+  *  - Fixed PLL prescaler defines for all AVR models and frequencies

+  *  - Fixed ENDPOINT_INT_IN and ENDPOINT_INT_OUT definitions

+  *  - Added interrupt driven keyboard and mouse device demos

+  *  - Combined USB_Device_ClearFeature and USB_Device_SetFeature requests into a single routine for code

+  *    size savings

+  *  - Added missing Pipe_GetCurrentPipe() macro to Pipe.h

+  *

+  *

+  *  \section Sec_ChangeLog130 Version 1.3.0 (080307)

+  *

+  *  - Unnecessary control endpoint config removed from device mode

+  *  - Fixed device standard request interpreter accidentally processing some class-specific requests

+  *  - Added USE_RAM_DESCRIPTORS and USE_EEPROM_DESCRIPTORS compile time options to instruct the library

+  *    to use descriptors stored in RAM or EEPROM rather than flash memory

+  *  - All demos now disable watchdog on startup, in case it has been enabled by fuses or the bootloader

+  *  - USB_DEV_OPT_LOWSPEED option now works correctly

+  *  - Added ability to set the USB options statically for a binary size reduction via the USE_STATIC_OPTIONS

+  *    compile time define

+  *  - USB_Init no longer takes a Mode parameter if compiled for a USB device with no host mode option, or

+  *    if forced to a particular mode via the USB_HOST_ONLY or USB_DEVICE_ONLY compile time options

+  *  - USB_Init no longer takes an Options parameter if options statically configured by USE_STATIC_OPTIONS

+  *  - Endpoint_Ignore_* and Pipe_Ignore_* made smaller by making the dummy variable non-volatile so that the

+  *    compiler can throw away the result more efficiently

+  *  - Added in an optional GroupID value to each scheduler entry, so that groups of tasks can once again be

+  *    controlled by the new Scheduler_SetGroupTaskMode() routine

+  *  - Added support for AT90USB162 and AT90USB82 AVR models

+  *  - Added support for the STK525 and STK526 boards

+  *  - Added support for custom board drivers to be supplied by selecting the board type as BOARD_USER, and

+  *    placing board drivers in {Application Directory}/Board/

+  *  - PLL is now stopped and USB clock is frozen when detached from host in device mode, to save power

+  *  - Joystick defines are now in synch with the schematics - orientation will be rotated for the USBKEY

+  *  - Fixed USB_DEV_IsUSBSuspended() - now checks the correct register

+  *  - Fixed data transfers to devices when in host mode

+  *  - Renamed USB_DEV_OPT_HIGHSPEED to USB_DEV_OPT_FULLSPEED and USB_HOST_IsDeviceHighSpeed() to

+  *    USB_HOST_IsDeviceFullSpeed() to be in line with the official USB speed names (to avoid confusion with

+  *    the real high speed mode, which is unavailable on the USB AVRs)

+  *

+  *

+  *  \section Sec_ChangeLog120 Version 1.2.0 (080204)

+  *

+  *  - Added USB_DeviceEnumerationComplete event for host mode

+  *  - Added new Scheduler_Init routine to prepare the scheduler, so that tasks can be started and

+  *    stopped before the scheduler has been started (via Scheduler_Start)

+  *  - Connection events in both Device and Host mode are now interrupt-driven, allowing the USB management

+  *    task to be stopped when the USB is not connected to a host or device

+  *  - All demos updated to stop the USB task when not in use via the appropriate USB events

+  *  - Mass Storage Host demo application updated to function correctly with all USB flash disks

+  *  - Mass Storage Host demo application now prints out the capacity and number of LUNs in the attached

+  *    device, and prints the first block as hexadecimal numbers rather than ASCII characters

+  *  - Endpoint and Pipe clearing routines now clear the Endpoint/Pipe interrupt and status flags

+  *  - Shifted error handling code in the host enum state machine to a single block, to reduce code complexity

+  *  - Added in DESCRIPTOR_TYPE, DESCRIPTOR_SIZE and DESCRIPTOR_CAST macros to make config descriptor processing

+  *    clearer in USB hosts and DESCRIPTOR_ADDRESS for convenience in USB devices

+  *  - Added in alloca macro to common.h, in case the user is using an old version of avr-lib-c missing the macro

+  *

+  *

+  *  \section Sec_ChangeLog110 Version 1.1.0 (080125)

+  *

+  *  - Fixed DCONNI interrupt being enabled accidentally after a USB reset

+  *  - Fixed DDISCI interrupt not being disabled when a device is not connected

+  *  - Added workaround for powerless pull-up devices causing false disconnect interrupts

+  *  - Added USB_DeviceEnumerationFailed event for Host mode

+  *  - AVR_HOST_GetDeviceConfigDescriptor routine no longer modifies ConfigSizePtr if a valid buffer

+  *    pointer is passed

+  *  - Added ALLOCABLE_BYTES to DynAlloc, and added code to make the size of key storage variables

+  *    dependant on size of memory parameters passed in via the user project's makefile

+  *  - Fixed incorrect device reset routine being called in USBTask

+  *  - Devices which do not connect within the standard 300mS are now supported

+  *  - Removed incorrect ATTR_PURE from Scheduler_SetTaskMode(), which was preventing tasks from being

+  *    started/stopped, as well as USB_InitTaskPointer(), which was breaking dual device/host USB projects

+  *  - Changed scheduler to use the task name rather than IDs for setting the task mode, eliminating the

+  *    need to have a task ID list

+  *  - ID transition interrupt now raises the appropriate device/host disconnect event if device attached

+  *  - Fixed double VBUS change (and VBUS -) event when detaching in device mode

+  *  - Added ability to disable ANSI terminal codes by the defining of DISABLE_TERMINAL_CODES in makefile

+  *  - Removed return from ConfigurePipe and ConfigureEndpoint functions - use Pipe_IsConfigured() and

+  *    Endpoint_IsConfigured() after calling the config functions to determine success
