- Use commit number as the basis for bcdDevice field (maximum is 2^16)
- Change iSerial from commit date to chip Unique ID
- Update both Firmware and Bootloader to use the same scheme (bcdDevice and iSerial)
- Cleanup of Bootloader code
- Split out build info CMake commands to a new file

USB - General
- Refactored descriptors
- Enabled/Disable USB endpoints
- Added debug flags for special features
- Code cleanup
- Interface count calculation based off of enabled endpoints
- Delayed wTotalLength calculation to simplify descriptor offsets
- Re-ordered endpoints and interfaces
- Added more debug output
- Added usbInitTime to show how long keyboard initialization took
  (Useful when debugging bad init sequences)
- Added function for usb_resume() which takes care of the resume sequence
  * Resume is now only called if packets are starting to timeout

USB - Special Options
- Added enableDeviceRestartOnUSBTimeout
  * A last resort hammer for bad USB Chipsets/OSs, don't use if you can help it
  * Disabled
- Added enableUSBResume
  * Enables host resume wake-up signalling, required to wake a computer from sleep
  * Enabled
- Added enableUSBLowPowerNegotiation
  * Enables power negotiation hack
  * Required to use firmware with an IPad and other hard-limit low-power USB hosts
  * Hasn't been tested with the recent changes
  * Disabled
- Added enableUSBSuspend
  * Enables power down events on host USB bus suspend
  * Enabled

USB - Keyboard
- Attempted to cleanup HID SET_REPORT
  * Works much better
  * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless)
    + Not present on other keyboards
    + SETUP -> OUT -> IN : This sequence is the problem
    + Specifically during the OUT phase
- Enabled

USB - CDC Virtual Serial Port
- Code cleanup
- Added convenience struct USBCDCLineCoding for easier debugging
- Attempted to cleanup CDC_SET_LING_CODING
  * Works much better
  * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless)
    + SETUP -> OUT -> IN : This sequence is the problem
    + Specifically during the OUT phase
    + Likely the same issues as HID SET_REPORT
- Enabled

USB - Mouse
- Enabled

USB - Joystick
- Disabled

USB - RawIO
- Initial code, API not used yet
- Disabled

DFU
- Updated load script, now faster

- Somewhat aggresive, may cause restarts if the keyboard/OS hasn't fully intialized the keyboard
- Added GET_IDLE handling and correct usage of SET_IDLE
- Initial implementation of idle send, commented out as it causes issues on Mac OSX for sleeping
  (keyboard has been working without it)
- MacOSX seems to have some sort of data corruption on the USB link, not sure why (other OSs have no issues)
- Cleaned up some code
- Added a longer sleep after the resume sequence to prevent possible issues sending keys too soon
  (may need to be increased more)

Ipad support now seems flaky, though Mac, Windows seems solid.
Init sequence on Linux seems slow, even though there are no errors.

- Maintains a sleep state variable (may be able to use as a signal in the future)
- On the first keypress, hold the RESUME signal for 10 ms (spec says between 1 and 15 ms)
- Removed some messages that were affecting sleep state

- Odd that this went unnoticed for sooooo long
- Fixes Mac OSX issue where keyboard freezes/hangs on a reboot
- Also adding missing code for usbMuxUart

- Each scan module now has a current change callback which passes the available current as a parameter
- No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration
- If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases)
- Now working with the Apple Ipad (no over-power messages)
- Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices)
- More effecient set_feature/clear_feature handling (device handler)
- Initial power handling via Interconnect (still needs work to get it more dynamic)

- Now enabled by default
- Added protection around remote jumps

- Implementation was completely wrong (has never worked properly)
- Now working in both NKRO and 6KRO modes
- Added more debugging code if things go wrong again

- Reverting old fix that no longer seems relevant after numerous recent USB fixes

- Adds proper flashMode support for all keyboards and microcontrollers (usb and serial)
- flashModeEnabled must be set to 1 otherwise it will only show an error
  * This is on purpose (somewhat dangerous feature as it allows remote flashing)
- Capability cleanup

- Media keys tested working on Linux/Windows/Mac (use Consumer control)
- Fixed enumeration delays
- Fixed virtual serial port configuration issues
- Fixed GET_REPORT and SET_REPORT
- Added intial descriptors and endpoints for Mouse and Joystick devices
- Split out the consumer and system control endpoint
- Added more fault debugging messages
- Added interface names to endpoints (visible in Windows Device Manager)
- Added KLL define for keyboard locale

- Fixed cli reflash mode set
- Cleaned up debugging code
- 4 500 000 baud seems to be reliable
- Fixed master selection (assumes slave node unless USB enumerates)

This reverts commit 622ea5d85f94be4b1694fdf08e30fa76eeb18fe4, reversing
changes made to c21439cb48.

Not working yet...

Use a consistent standard - Tabs in front for indenting, spaces after for anything else. This way everything stays nice and lined up while also letting users change there prefered indent level. Most of the new files from Haata where already in this format.

- Ignoring (which is done by default)
- Device, Interface and Endpoint variants

- CLEAR_FEATURE unset is currently causing the keyboarod to freeze
- Though not ideal, it seems harmless to ignore this USB Control Packet
- Tested working on a Mac Mini (Yosemite)

- Currently actual detection commented out due to issues

- Had to re-write descriptor to support Windows 8.1 while still working with Mac OSX
- NKRO keyboard is now more bandwidth intensive as all the keys must be updated at the same time
  (due to 8.1 bug in the HID spec)

- Added NKRO descriptor
- Added NKRO HID descriptor
- Updated boot HID descriptor
- Fixed many bugs with the pjrc ARM usb stack (with USB HID)

- Changed static variables to const that should have been const
- Updated CMake files to prepare for MCHCK custom bootloader
- Changed the USB ID numbers and ID number for bootloader
- Only generate DFU or Teensy binary image, not both
- Fixed RAM and FLASH calculator
- Added missing license in delay.c/h (much of it was taken from Teensy source though I've changed a bunch of it)
- Prepared mk20dx.c for upcoming bootloader addition
- mk20dx.h cleanup
- Reduced the MCHCK based flash size for the application image (bootloader changes requires more flash space)
- Fixed bugs in macro.c
- Added keyHold cli command
- Added show pending events debug message for PartialMap macro module

- Cleaned up Macro and USB callback naming
- Added security jumper for automated reload (MCHCK based only)
- Added additional LED position

- Requires special string to be compared with the bootloader and VBAT register file

- McHCK uses FLL instead of the PLL for USB (startup, not usb init)
- Added optional debug for the pjrc USB module
- Cleaned up compiler flags

- Basic compilation and loading is working
- LED can be turned on/off
- USB not yet working

- For potential bug fixes
- Not copied verbatim, some additions were left out

- reset   -> Simulates power cycle (Not yet compatible with AVR)
- reload  -> Sets the device into firmware reload mode
- led     -> Toggles the error LED
- version -> Displays detailed version information (additions to CMake files was necessary, might have broken Windows builds...)

* Initial cli code

- Also a bit of general house-keeping

- CDC Output seems to be working
- USB Keyboard output has not been tested, but is "ready"
- UART and Timers have not been tested, or fully utilized
- Issues using Timer 0
- Initial template for MBC-55X Scan module (only module currently compatible with the arm build)
- Updated the interface to the AVR usb module for symmetry with the ARM usb module
- Much gutting was done to the Teensy 3 usb keyboard module, though not in an ideal state yet
