415 * - Unnecessary control endpoint config removed from device mode
416 * - Fixed device standard request interpreter accidentally processing some class-specific requests
417 * - Added USE_RAM_DESCRIPTORS and USE_EEPROM_DESCRIPTORS compile time options to instruct the library
418 * to use descriptors stored in RAM or EEPROM rather than flash memory
419 * - All demos now disable watchdog on startup, in case it has been enabled by fuses or the bootloader
420 * - USB_DEV_OPT_LOWSPEED option now works correctly
421 * - Added ability to set the USB options statically for a binary size reduction via the USE_STATIC_OPTIONS
422 * compile time define

425 * - USB_Init no longer takes an Options parameter if options statically configured by USE_STATIC_OPTIONS
426 * - Endpoint_Ignore_* and Pipe_Ignore_* made smaller by making the dummy variable non-volatile so that the
427 * compiler can throw away the result more efficiently
428 * - Added in an optional GroupID value to each scheduler entry, so that groups of tasks can once again be
429 * controlled by the new Scheduler_SetGroupTaskMode() routine

431 * - Added support for the STK525 and STK526 boards

433 * placing board drivers in {Application Directory}/Board/
434 * - PLL is now stopped and USB clock is frozen when detached from host in device mode, to save power
435 * - Joystick defines are now in synch with the schematics - orientation will be rotated for the USBKEY
436 * - Fixed USB_DEV_IsUSBSuspended() - now checks the correct register
437 * - Fixed data transfers to devices when in host mode
438 * - Renamed USB_DEV_OPT_HIGHSPEED to USB_DEV_OPT_FULLSPEED and USB_HOST_IsDeviceHighSpeed() to
439 * USB_HOST_IsDeviceFullSpeed() to be in line with the official USB speed names (to avoid confusion with
440 * the real high speed mode, which is unavailable on the USB AVRs)

445 * - Added USB_DeviceEnumerationComplete event for host mode

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

451 * - Mass Storage Host demo application updated to function correctly with all USB flash disks
452 * - Mass Storage Host demo application now prints out the capacity and number of LUNs in the attached
453 * device, and prints the first block as hexadecimal numbers rather than ASCII characters

455 * - Shifted error handling code in the host enum state machine to a single block, to reduce code complexity
456 * - Added in DESCRIPTOR_TYPE, DESCRIPTOR_SIZE and DESCRIPTOR_CAST macros to make config descriptor processing
457 * clearer in USB hosts and DESCRIPTOR_ADDRESS for convenience in USB devices
458 * - Added in alloca macro to common.h, in case the user is using an old version of avr-lib-c missing the macro

471 * - Fixed incorrect device reset routine being called in USBTask
472 * - Devices which do not connect within the standard 300mS are now supported

476 * need to have a task ID list
