715 * - Devices which do not connect within the standard 300mS are now supported
716 * - Removed incorrect ATTR_PURE from Scheduler_SetTaskMode(), which was preventing tasks from being
717 * started/stopped, as well as USB_InitTaskPointer(), which was breaking dual device/host USB projects
718 * - Changed scheduler to use the task name rather than IDs for setting the task mode, eliminating the
719 * need to have a task ID list
720 * - ID transistion interrupt now raises the appropriate device/host disconnect event if device attached
721 * - Fixed double VBUS change (and VBUS -) event when detatching in device mode
722 * - Added ability to disable ANSI terminal codes by the defining of DISABLE_TERMINAL_CODES in makefile
723 * - Removed return from ConfigurePipe and ConfigureEndpoint functions - use Pipe_IsConfigured() and
724 * Endpoint_IsConfigured() after calling the config functions to determine success
