-This file documents changes in the firmware-only USB driver for atmel's AVR
-microcontrollers. New entries are always appended to the end of the file.
-Scroll down to the bottom to see the most recent changes.
-
-2005-04-01:
-  - Implemented endpoint 1 as interrupt-in endpoint.
-  - Moved all configuration options to usbconfig.h which is not part of the
-    driver.
-  - Changed interface for usbVendorSetup().
-  - Fixed compatibility with ATMega8 device.
-  - Various minor optimizations.
-
-2005-04-11:
-  - Changed interface to application: Use usbFunctionSetup(), usbFunctionRead()
-    and usbFunctionWrite() now. Added configuration options to choose which
-    of these functions to compile in.
-  - Assembler module delivers receive data non-inverted now.
-  - Made register and bit names compatible with more AVR devices.
-
-2005-05-03:
-  - Allow address of usbRxBuf on any memory page as long as the buffer does
-    not cross 256 byte page boundaries.
-  - Better device compatibility: works with Mega88 now.
-  - Code optimization in debugging module.
-  - Documentation updates.
-
-2006-01-02:
-  - Added (free) default Vendor- and Product-IDs bought from voti.nl.
-  - Added USBID-License.txt file which defines the rules for using the free
-    shared VID/PID pair.
-  - Added Readme.txt to the usbdrv directory which clarifies administrative
-    issues.
-
-2006-01-25:
-  - Added "configured state" to become more standards compliant.
-  - Added "HALT" state for interrupt endpoint.
-  - Driver passes the "USB Command Verifier" test from usb.org now.
-  - Made "serial number" a configuration option.
-  - Minor optimizations, we now recommend compiler option "-Os" for best
-    results.
-  - Added a version number to usbdrv.h
-
-2006-02-03:
-  - New configuration variable USB_BUFFER_SECTION for the memory section where
-    the USB rx buffer will go. This defaults to ".bss" if not defined. Since
-    this buffer MUST NOT cross 256 byte pages (not even touch a page at the
-    end), the user may want to pass a linker option similar to
-    "-Wl,--section-start=.mybuffer=0x800060".
-  - Provide structure for usbRequest_t.
-  - New defines for USB constants.
-  - Prepared for HID implementations.
-  - Increased data size limit for interrupt transfers to 8 bytes.
-  - New macro usbInterruptIsReady() to query interrupt buffer state.
-
-2006-02-18:
-  - Ensure that the data token which is sent as an ack to an OUT transfer is
-    always zero sized. This fixes a bug where the host reports an error after
-    sending an out transfer to the device, although all data arrived at the
-    device.
-  - Updated docs in usbdrv.h to reflect changed API in usbFunctionWrite().
-
-* Release 2006-02-20
-
-  - Give a compiler warning when compiling with debugging turned on.
-  - Added Oleg Semyonov's changes for IAR-cc compatibility.
-  - Added new (optional) functions usbDeviceConnect() and usbDeviceDisconnect()
-    (also thanks to Oleg!).
-  - Rearranged tests in usbPoll() to save a couple of instructions in the most
-    likely case that no actions are pending.
-  - We need a delay between the SET ADDRESS request until the new address
-    becomes active. This delay was handled in usbPoll() until now. Since the
-    spec says that the delay must not exceed 2ms, previous versions required
-    aggressive polling during the enumeration phase. We have now moved the
-    handling of the delay into the interrupt routine.
-  - We must not reply with NAK to a SETUP transaction. We can only achieve this
-    by making sure that the rx buffer is empty when SETUP tokens are expected.
-    We therefore don't pass zero sized data packets from the status phase of
-    a transfer to usbPoll(). This change MAY cause troubles if you rely on
-    receiving a less than 8 bytes long packet in usbFunctionWrite() to
-    identify the end of a transfer. usbFunctionWrite() will NEVER be called
-    with a zero length.
-
-* Release 2006-03-14
-
-  - Improved IAR C support: tiny memory model, more devices
-  - Added template usbconfig.h file under the name usbconfig-prototype.h
-
-* Release 2006-03-26
-
-  - Added provision for one more interrupt-in endpoint (endpoint 3).
-  - Added provision for one interrupt-out endpoint (endpoint 1).
-  - Added flowcontrol macros for USB.
-  - Added provision for custom configuration descriptor.
-  - Allow ANY two port bits for D+ and D-.
-  - Merged (optional) receive endpoint number into global usbRxToken variable.
-  - Use USB_CFG_IOPORTNAME instead of USB_CFG_IOPORT. We now construct the
-    variable name from the single port letter instead of computing the address
-    of related ports from the output-port address.
-
-* Release 2006-06-26
-
-  - Updated documentation in usbdrv.h and usbconfig-prototype.h to reflect the
-    new features.
-  - Removed "#warning" directives because IAR does not understand them. Use
-    unused static variables instead to generate a warning.
-  - Do not include <avr/io.h> when compiling with IAR.
-  - Introduced USB_CFG_DESCR_PROPS_* in usbconfig.h to configure how each
-    USB descriptor should be handled. It is now possible to provide descriptor
-    data in Flash, RAM or dynamically at runtime.
-  - STALL is now a status in usbTxLen* instead of a message. We can now conform
-    to the spec and leave the stall status pending until it is cleared.
-  - Made usbTxPacketCnt1 and usbTxPacketCnt3 public. This allows the
-    application code to reset data toggling on interrupt pipes.
-
-* Release 2006-07-18
-
-  - Added an #if !defined __ASSEMBLER__ to the warning in usbdrv.h. This fixes
-    an assembler error.
-  - usbDeviceDisconnect() takes pull-up resistor to high impedance now.
-
-* Release 2007-02-01
-
-  - Merged in some code size improvements from usbtiny (thanks to Dick
-    Streefland for these optimizations!)
-  - Special alignment requirement for usbRxBuf not required any more. Thanks
-    again to Dick Streefland for this hint!
-  - Reverted to "#warning" instead of unused static variables -- new versions
-    of IAR CC should handle this directive.
-  - Changed Open Source license to GNU GPL v2 in order to make linking against
-    other free libraries easier. We no longer require publication of the
-    circuit diagrams, but we STRONGLY encourage it. If you improve the driver
-    itself, PLEASE grant us a royalty free license to your changes for our
-    commercial license.
-
-* Release 2007-03-29
-
-  - New configuration option "USB_PUBLIC" in usbconfig.h.
-  - Set USB version number to 1.10 instead of 1.01.
-  - Code used USB_CFG_DESCR_PROPS_STRING_DEVICE and
-    USB_CFG_DESCR_PROPS_STRING_PRODUCT inconsistently. Changed all occurrences
-    to USB_CFG_DESCR_PROPS_STRING_PRODUCT.
-  - New assembler module for 16.5 MHz RC oscillator clock with PLL in receiver
-    code.
-  - New assembler module for 16 MHz crystal.
-  - usbdrvasm.S contains common code only, clock-specific parts have been moved
-    to usbdrvasm12.S, usbdrvasm16.S and usbdrvasm165.S respectively.
-
-* Release 2007-06-25
-
-  - 16 MHz module: Do SE0 check in stuffed bits as well.
-
-* Release 2007-07-07
-
-  - Define hi8(x) for IAR compiler to limit result to 8 bits. This is necessary
-    for negative values.
-  - Added 15 MHz module contributed by V. Bosch.
-  - Interrupt vector name can now be configured. This is useful if somebody
-    wants to use a different hardware interrupt than INT0.
-
-* Release 2007-08-07
-
-  - Moved handleIn3 routine in usbdrvasm16.S so that relative jump range is
-    not exceeded.
-  - More config options: USB_RX_USER_HOOK(), USB_INITIAL_DATATOKEN,
-    USB_COUNT_SOF
-  - USB_INTR_PENDING can now be a memory address, not just I/O
-
-* Release 2007-09-19
-
-  - Split out common parts of assembler modules into separate include file
-  - Made endpoint numbers configurable so that given interface definitions
-    can be matched. See USB_CFG_EP3_NUMBER in usbconfig-prototype.h.
-  - Store endpoint number for interrupt/bulk-out so that usbFunctionWriteOut()
-    can handle any number of endpoints.
-  - Define usbDeviceConnect() and usbDeviceDisconnect() even if no
-    USB_CFG_PULLUP_IOPORTNAME is defined. Directly set D+ and D- to 0 in this
-    case.
-
-* Release 2007-12-01
-
-  - Optimize usbDeviceConnect() and usbDeviceDisconnect() for less code size
-    when USB_CFG_PULLUP_IOPORTNAME is not defined.
-
-* Release 2007-12-13
-
-  - Renamed all include-only assembler modules from *.S to *.inc so that
-    people don't add them to their project sources.
-  - Distribute leap bits in tx loop more evenly for 16 MHz module.
-  - Use "macro" and "endm" instead of ".macro" and ".endm" for IAR
-  - Avoid compiler warnings for constant expr range by casting some values in
-    USB descriptors.
-
-* Release 2008-01-21
-
-  - Fixed bug in 15 and 16 MHz module where the new address set with
-    SET_ADDRESS was already accepted at the next NAK or ACK we send, not at
-    the next data packet we send. This caused problems when the host polled
-    too fast. Thanks to Alexander Neumann for his help and patience debugging
-    this issue!
-
-* Release 2008-02-05
-
-  - Fixed bug in 16.5 MHz module where a register was used in the interrupt
-    handler before it was pushed. This bug was introduced with version
-    2007-09-19 when common parts were moved to a separate file.
-  - Optimized CRC routine (thanks to Reimar Doeffinger).
-
-* Release 2008-02-16
-
-  - Removed outdated IAR compatibility stuff (code sections).
-  - Added hook macros for USB_RESET_HOOK() and USB_SET_ADDRESS_HOOK().
-  - Added optional routine usbMeasureFrameLength() for calibration of the
-    internal RC oscillator.
-
-* Release 2008-02-28
-
-  - USB_INITIAL_DATATOKEN defaults to USBPID_DATA1 now, which means that we
-    start with sending USBPID_DATA0.
-  - Changed defaults in usbconfig-prototype.h
-  - Added free USB VID/PID pair for MIDI class devices
-  - Restructured AVR-USB as separate package, not part of PowerSwitch any more.
-
-* Release 2008-04-18
-
-  - Restructured usbdrv.c so that it is easier to read and understand.
-  - Better code optimization with gcc 4.
-  - If a second interrupt in endpoint is enabled, also add it to config
-    descriptor.
-  - Added config option for long transfers (above 254 bytes), see
-    USB_CFG_LONG_TRANSFERS in usbconfig.h.
-  - Added 20 MHz module contributed by Jeroen Benschop.
-
-* Release 2008-05-13
-
-  - Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length
-    was not incremented, pointer to length was incremented instead.
-  - Added code to command line tool(s) which claims an interface. This code
-    is disabled by default, but may be necessary on newer Linux kernels.
-  - Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING".
-  - New header "usbportability.h" prepares ports to other development
-    environments.
-  - Long transfers (above 254 bytes) did not work when usbFunctionRead() was
-    used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!]
-  - In hiddata.c (example code for sending/receiving data over HID), use
-    USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so
-    that we need not claim the interface.
-  - in usbPoll() loop 20 times polling for RESET state instead of 10 times.
-    This accounts for the higher clock rates we now support.
-  - Added a module for 12.8 MHz RC oscillator with PLL in receiver loop.
-  - Added hook to SOF code so that oscillator can be tuned to USB frame clock.
-  - Added timeout to waitForJ loop. Helps preventing unexpected hangs.
-  - Added example code for oscillator tuning to libs-device (thanks to
-    Henrik Haftmann for the idea to this routine).
-  - Implemented option USB_CFG_SUPPRESS_INTR_CODE.
-
-* Release 2008-10-22
-
-  - Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and
-    similar, not offset of 0x20 needs to be added.
-  - Allow distribution under GPLv3 for those who have to link against other
-    code distributed under GPLv3.
-
-* Release 2008-11-26
-
-  - Removed libusb-win32 dependency for hid-data example in Makefile.windows.
-    It was never required and confused many people.
-  - Added extern uchar usbRxToken to usbdrv.h.
-  - Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser.
-
-* Release 2009-03-23
-
-  - Hid-mouse example used settings from hid-data example, fixed that.
-  - Renamed project to V-USB due to a trademark issue with Atmel(r).
-  - Changed CommercialLicense.txt and USBID-License.txt to make the
-    background of USB ID registration clearer.
-
-* Release 2009-04-15
-
-  - Changed CommercialLicense.txt to reflect the new range of PIDs from
-    Jason Kotzin.
-  - Removed USBID-License.txt in favor of USB-IDs-for-free.txt and
-    USB-ID-FAQ.txt
-  - Fixed a bug in the 12.8 MHz module: End Of Packet decection was made in
-    the center between bit 0 and 1 of each byte. This is where the data lines
-    are expected to change and the sampled data may therefore be nonsense.
-    We therefore check EOP ONLY if bits 0 AND 1 have both been read as 0 on D-.
-  - Fixed a bitstuffing problem in the 16 MHz module: If bit 6 was stuffed,
-    the unstuffing code in the receiver routine was 1 cycle too long. If
-    multiple bytes had the unstuffing in bit 6, the error summed up until the
-    receiver was out of sync.
-  - Included option for faster CRC routine.
-    Thanks to Slawomir Fras (BoskiDialer) for this code!
-  - Updated bits in Configuration Descriptor's bmAttributes according to
-    USB 1.1 (in particular bit 7, it is a must-be-set bit now).
-
-* Release 2009-08-22
-
-  - Moved first DBG1() after odDebugInit() in all examples.
-  - Use vector INT0_vect instead of SIG_INTERRUPT0 if defined. This makes
-    V-USB compatible with the new "p" suffix devices (e.g. ATMega328p).
-  - USB_CFG_CLOCK_KHZ setting is now required in usbconfig.h (no default any
-    more).
-  - New option USB_CFG_DRIVER_FLASH_PAGE allows boot loaders on devices with
-    more than 64 kB flash.
-  - Built-in configuration descriptor allows custom definition for second
-    endpoint now.
-
-* Release 2010-07-15
