353 * size savings
354 * - Added missing Pipe_GetCurrentPipe() macro to Pipe.h
355 *
356 *
357 * \section Sec_ChangeLog130 Version 1.3.0 - Released March 7th 2008
358 *
359 * - Unneccesary control endpoint config removed from device mode
360 * - Fixed device standard request interpreter accidentally processing some class-specific requests
361 * - Added USE_RAM_DESCRIPTORS and USE_EEPROM_DESCRIPTORS compile time options to instruct the library
362 * to use descriptors stored in RAM or EEPROM rather than flash memory
363 * - All demos now disable watchdog on startup, in case it has been enabled by fuses or the bootloader
364 * - USB_DEV_OPT_LOWSPEED option now works correctly
365 * - Added ability to set the USB options statically for a binary size reduction via the USE_STATIC_OPTIONS
366 * compile time define
367 * - USB_Init no longer takes a Mode parameter if compiled for a USB device with no host mode option, or
368 * if forced to a particular mode via the USB_HOST_ONLY or USB_DEVICE_ONLY compile time options
369 * - USB_Init no longer takes an Options parameter if options statically configured by USE_STATIC_OPTIONS
370 * - Endpoint_Ignore_* and Pipe_Ignore_* made smaller by making the dummy variable non-volatile so that the
371 * compiler can throw away the result more efficiently
372 * - Added in an optional GroupID value to each scheduler entry, so that groups of tasks can once again be
373 * controlled by the new Scheduler_SetGroupTaskMode() routine
374 * - Added support for AT90USB162 and AT90USB82 AVR models
375 * - Added support for the STK525 and STK526 boards
376 * - Added support for custom board drivers to be supplied by selecting the board type as BOARD_USER, and
377 * placing board drivers in {Application Directory}/Board/
378 * - PLL is now stopped and USB clock is frozen when detatched from host in device mode, to save power
379 * - Joystick defines are now in synch with the schematics - orientation will be rotated for the USBKEY
380 * - Fixed USB_DEV_IsUSBSuspended() - now checks the correct register
381 * - Fixed data transfers to devices when in host mode
382 * - Renamed USB_DEV_OPT_HIGHSPEED to USB_DEV_OPT_FULLSPEED and USB_HOST_IsDeviceHighSpeed() to
383 * USB_HOST_IsDeviceFullSpeed() to be in line with the official USB speed names (to avoid confusion with
384 * the real high speed mode, which is unavailable on the USB AVRs)
385 *
386 *
387 * \section Sec_ChangeLog120 Version 1.2.0 - Released February 4th, 2008
388 *
389 * - Added USB_DeviceEnumerationComplete event for host mode
390 * - Added new Scheduler_Init routine to preprepare the scheduler, so that tasks can be started and
391 * stopped before the scheduler has been started (via Scheduler_Start)
392 * - Connection events in both Device and Host mode are now interrupt-driven, allowing the USB management
393 * task to be stopped when the USB is not connected to a host or device
394 * - All demos updated to stop the USB task when not in use via the appropriate USB events
395 * - Mass Storage Host demo application updated to function correctly with all USB flash disks
396 * - Mass Storage Host demo application now prints out the capacity and number of LUNs in the attached
397 * device, and prints the first block as hexadecimal numbers rather than ASCII characters
398 * - Endpoint and Pipe clearing routines now clear the Endpoint/Pipe interrupt and status flags
399 * - Shifted error handling code in the host enum state machine to a single block, to reduce code complexity
400 * - Added in DESCRIPTOR_TYPE, DESCRIPTOR_SIZE and DESCRIPTOR_CAST macros to make config descriptor processing
401 * clearer in USB hosts and DESCRIPTOR_ADDRESS for convenience in USB devices
402 * - Added in alloca macro to common.h, in case the user is using an old version of avr-lib-c missing the macro
403 *
404 *
405 * \section Sec_ChangeLog130 Version 1.1.0 - Released January 25th 2008
406 *
407 * - Fixed DCONNI interrupt being enabled accidentally after a USB reset
408 * - Fixed DDISCI interrupt not being disabled when a device is not connected
409 * - Added workaround for powerless pullup devices causing false disconnect interrupts
410 * - Added USB_DeviceEnumerationFailed event for Host mode
411 * - AVR_HOST_GetDeviceConfigDescriptor routine no longer modifies ConfigSizePtr if a valid buffer
412 * pointer is passed
413 * - Added ALLOCABLE_BYTES to DynAlloc, and added code to make the size of key storage variables
414 * dependant on size of memory parameters passed in via the user project's makefile
415 * - Fixed incorrect device reset routine being called in USBTask
416 * - Devices which do not connect within the standard 300mS are now supported
417 * - Removed incorrect ATTR_PURE from Scheduler_SetTaskMode(), which was preventing tasks from being
418 * started/stopped, as well as USB_InitTaskPointer(), which was breaking dual device/host USB projects
419 * - Changed scheduler to use the task name rather than IDs for setting the task mode, eliminating the
420 * need to have a task ID list
421 * - ID transistion interrupt now raises the appropriate device/host disconnect event if device attached
422 * - Fixed double VBUS change (and VBUS -) event when detatching in device mode
423 * - Added ability to disable ANSI terminal codes by the defining of DISABLE_TERMINAL_CODES in makefile
424 * - Removed return from ConfigurePipe and ConfigureEndpoint functions - use Pipe_IsConfigured() and
425 * Endpoint_IsConfigured() after calling the config functions to determine success
