369 * controlled by the new Scheduler_SetGroupTaskMode() routine
370 * - Added support for AT90USB162 and AT90USB82 AVR models
371 * - Added support for the STK525 and STK526 boards
372 * - Added support for custom board drivers to be supplied by selecting the board type as BOARD_USER, and
373 * placing board drivers in {Application Directory}/Board/
374 * - PLL is now stopped and USB clock is frozen when detatched from host in device mode, to save power
375 * - Joystick defines are now in synch with the schematics - orientation will be rotated for the USBKEY
376 * - Fixed USB_DEV_IsUSBSuspended() - now checks the correct register
377 * - Fixed data transfers to devices when in host mode
378 * - Renamed USB_DEV_OPT_HIGHSPEED to USB_DEV_OPT_FULLSPEED and USB_HOST_IsDeviceHighSpeed() to
379 * USB_HOST_IsDeviceFullSpeed() to be in line with the official USB speed names (to avoid confusion with
380 * the real high speed mode, which is unavailable on the USB AVRs)
383 * \section Sec_ChangeLog120 Version 1.2.0 - Released February 4th, 2008
385 * - Added USB_DeviceEnumerationComplete event for host mode
386 * - Added new Scheduler_Init routine to preprepare the scheduler, so that tasks can be started and
387 * stopped before the scheduler has been started (via Scheduler_Start)
388 * - Connection events in both Device and Host mode are now interrupt-driven, allowing the USB management
389 * task to be stopped when the USB is not connected to a host or device
390 * - All demos updated to stop the USB task when not in use via the appropriate USB events
391 * - Mass Storage Host demo application updated to function correctly with all USB flash disks
392 * - Mass Storage Host demo application now prints out the capacity and number of LUNs in the attached
393 * device, and prints the first block as hexadecimal numbers rather than ASCII characters
394 * - Endpoint and Pipe clearing routines now clear the Endpoint/Pipe interrupt and status flags
395 * - Shifted error handling code in the host enum state machine to a single block, to reduce code complexity
396 * - Added in DESCRIPTOR_TYPE, DESCRIPTOR_SIZE and DESCRIPTOR_CAST macros to make config descriptor processing
397 * clearer in USB hosts and DESCRIPTOR_ADDRESS for convenience in USB devices
398 * - Added in alloca macro to common.h, in case the user is using an old version of avr-lib-c missing the macro
401 * \section Sec_ChangeLog130 Version 1.1.0 - Released January 25th 2008
403 * - Fixed DCONNI interrupt being enabled accidentally after a USB reset
404 * - Fixed DDISCI interrupt not being disabled when a device is not connected
405 * - Added workaround for powerless pullup devices causing false disconnect interrupts
406 * - Added USB_DeviceEnumerationFailed event for Host mode
407 * - AVR_HOST_GetDeviceConfigDescriptor routine no longer modifies ConfigSizePtr if a valid buffer
409 * - Added ALLOCABLE_BYTES to DynAlloc, and added code to make the size of key storage variables
410 * dependant on size of memory parameters passed in via the user project's makefile
411 * - Fixed incorrect device reset routine being called in USBTask
412 * - Devices which do not connect within the standard 300mS are now supported
413 * - Removed incorrect ATTR_PURE from Scheduler_SetTaskMode(), which was preventing tasks from being
414 * started/stopped, as well as USB_InitTaskPointer(), which was breaking dual device/host USB projects
415 * - Changed scheduler to use the task name rather than IDs for setting the task mode, eliminating the
416 * need to have a task ID list
417 * - ID transistion interrupt now raises the appropriate device/host disconnect event if device attached
418 * - Fixed double VBUS change (and VBUS -) event when detatching in device mode
419 * - Added ability to disable ANSI terminal codes by the defining of DISABLE_TERMINAL_CODES in makefile
420 * - Removed return from ConfigurePipe and ConfigureEndpoint functions - use Pipe_IsConfigured() and
421 * Endpoint_IsConfigured() after calling the config functions to determine success
