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