51 * <b>Changed:</b>
52 * - Deprecated psuedo-scheduler and removed dynamic memory allocator from the library (first no longer needed and second unused)
53 * - The device-mode CALLBACK_USB_GetDescriptor() function now has an extra parameter so that the memory space in which the requested
54 * descriptor is located can be specified. This means that descriptors can now be located in multiple memory spaces within a device.
55 * - Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality
56 * - Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead
57 * - Extended USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch
58 * - Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning,
59 * no need to call Dataflash_ToggleSelectedChipCS() afterwards
60 * - Low level API MIDI device demo no longer blocks if a note change event is sent while the endpoint is not ready
61 * - Pipe_GetErrorFlags() now returns additional error flags for overflow and underflow errors
62 * - Pipe stream functions now automatically set the correct pipe token, so that bidirectional pipes can be used
63 * - Pipe_ConfigurePipe() now automatically defaults IN pipes to accepting infinite IN requests, this can still be changed by calling
64 * the existing Pipe_SetFiniteINRequests() function
65 * - Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case
66 * - Host mode demos now use sane terminal escape codes, so that text is always readable and events/program output is visually distinguished
67 * from oneanother using foreground colours
68 * - Internal per-device preprocessing conditions changed to per-device series rather than per-controller group for finer-grain
69 * internal control
70 * - Interrupts are no longer disabled during the processing of Control Requests on the default endpoint while in device mode
71 * - AudioOutput demos now always output to board LEDs, regardless of output mode (removed AUDIO_OUT_LEDS project option)
72 * - Removed SINGLE_DEVICE_CONFIGURATION compile time option in favour of the new FIXED_NUM_CONFIGURATIONS option so that the exact number
73 * of device configurations can be defined statically
74 * - Removed VBUS events, as they are already exposed to the user application via the regular device connection and disconnection events
75 * - Renamed and altered existing events to properly seperate out Host and Device mode events
76 *
77 * <b>Fixed:</b>
78 * - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed to fix
79 * bootloaders on some of the USB AVR devices where avr-libc erronously defines RAMPZ
80 * - Fixes to MassStorageHost for better device compatibility (increase command timeout, change MassStore_WaitForDataReceived()
81 * to only unfreeze and check one data pipe at a time) to prevent incorrect device enumerations and freezes while trasferring data
82 * - Make Pipe_ConfigurePipe() mask the given endpoint number against PIPE_EPNUM_MASK to ensure the endpoint IN direction bit is
83 * cleared to prevent endpoint type corruption
84 * - Fixed issue opening CDC-ACM ports on hosts when the CDC device tries to send data before the host has set the line encoding
85 * - Fixed USB_OPT_MANUAL_PLL option being ignored during device disconnects on some models (thanks to Brian Dickman)
86 * - Fixed documentation mentioning Pipe_GetCurrentToken() function when correct function name is Pipe_GetPipeToken()
87 * - Fixed ADC driver for the ATMEGA32U4 and ATMEGA16U4 (thanks to Opendous Inc.)
88 * - Fixed CDCHost demo unfreezing the pipes at the point of configuration, rather than use
89 * - Fixed MassStorage demo not clearing the reset flag when a Mass Storage Reset is issued while not processing a command
90 * - Fixed USB_Host_SendControlRequest() not re-suspending the USB bus when initial device ready-wait fails
91 * - Fixed USB Pad regulator not being disabled on some AVR models when the USB_OPT_REG_DISABLED option is used
92 * - Fixed Host mode to Device mode UID change not causing a USB Disconnect event when a device was connected
93 * - Fixed Mouse/Keyboard demos not performing the correct arithmetic on the Idle period at the right times (thanks to Brian Dickman)
94 * - Fixed GenericHID failing HID class tests due to incorrect Logical Minimum and Logical Maximum values (thanks to Søren Greiner)
95 * - Fixed incorrect PIPE_EPNUM_MASK mask causing pipe failures on devices with endpoint addresses of 8 and above (thanks to John Andrews)
96 * - Fixed report data alignment issues in the MouseHostWithParser demo when X and Y movement data size is not a multiple of 8 bits
97 * - Fixed HID Report Descriptor Parser not correctly resetting internal states when a REPORT ID element is encountered
98 * - Fixed incorrect BUTTONS_BUTTON1 for the STK526 target
99 * - Fixed RNDIS demos freezing when more than one connection was attempted simultaneously, causing memory corruption
100 * - Fixed USBtoSerial demo receiving noise from the USART due to pullup not being enabled
101 *

108 * - Fixed Mouse and Keyboard device demos not acting in accordance with the HID specification for idle periods (thanks to Brian Dickman)
109 * - Removed support for endpoint/pipe non-control interrupts; these did not act in the way users expected, and had many subtle issues

111 * - Moved control endpoint interrupt handling into the library itself, enable via the new INTERRUPT_CONTROL_ENDPOINT token
112 * - Fixed CDCHost not clearing configured pipes and resetting configured pipes mask when a partially enumerated invalid CDC
113 * interface is skipped
114 * - Clarified the size of library tokens which accept integer values in the Compile Time Tokens page, values now use the smallest datatype
115 * inside the library that is able to hold their defined value to save space
116 * - Removed DESCRIPTOR_ADDRESS() macro as it was largely supurflous and only served to obfuscate code
117 * - Rewritten event system to remove all macros, to make user code clearer
118 * - Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley)
119 * - Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code

125 * - Moved out each demos' functionality library files (e.g. Ring Buffer library) to /Lib directories for a better directory structure
126 * - Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt
127 * - Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition
128 * becomes true
129 *
130 *

142 * to early-abort (thanks to Dmitry Maksimov)
143 * - Move StdRequestType.h, StreamCallbacks.h, USBMode.h from the LowLevel USB driver directory to the HighLevel USB driver directory,

157 * pipes can be used with the function
158 * - The USB Host management task now saves and restores the currently selected pipe before and after the task completes
159 * - Fixed GenericHIDHost demo report write routine incorrect for control type requests (thanks to Andrei Krainev)

188 * - The Endpoint control stream functions now correctly send a ZLP to the host when less data than requested is sent

334 * timing requirements.

351 * - Changed prototype of GetDescriptor, so that it now returns the descriptor size (or zero if the descriptor doesn't exist)

423 * - Fixed MIDI demo, corrected Audio Streaming descriptor to follow the MIDI-specific AS structure
