The first gigabyte fix, was to always force the keyboard into boot protocol mode, which appeared to work well for all of the keyboards I tried.

Unforationally it caused issues with some wireless keyboard/mouse combo packages, including some logitech and some microsoft keyboards.

This version instead, I created a list (currently only one vendor id), of vendor id:product id, that need to be forced into boot mode.  Knowing that if there is one keyboard vendor with this N key rollover feature, there are probably others.  So while this list can be expanded, this requires users to update library.  So added a method forceBootProtocol method to keyboard class that allows the user to try it out without needing to update the library sources.

The mouse test program has example of either setting it before the keyboard is initiated, as well as another way that when a connection is found it asks for the vendor id, and if it is the one of my gigabyte keyboard, it calls the function then.

While doing this I found some of the query functions like idVendor on the keyboard class would not compile as the keyboard object has multiple inheritence and both base classes have this.  So like the joystick objects I added these to the top level function and these functions will direct the calls to the approrpriate places.

Support for using the Microsoft XBox 360 wireless receiver for windows
to be able to communicate with XBox 360 wireless controllers.

In theory this should support up to 4 controllers.  So far I have only
tested with one as I only have one.

Added a joystick only test that should support up to 4 joystick objects.

Added support for Joysticks, that on some of them we can not receive more of the Joysticks axis.  So far mainly on PS3 and PS4.  So you can now get the Gyro/accel stuff.  You get feedback on the DS4 touch area, PS3 you can get the pressure values on several of the buttons.  LIke the RT/LT ones.

In addition added some support for Rumble.  So far it appears to be working somewhat on the PS3 and PS4 controllers.  On the PS4 you can also set the RGB LED light values and on the PS3 you can set the 4 LEDS on the front., which are normally used to say which controller it is.

While the other Joystick objects currently supported by the USB Host
code are driven by HID data, the Xbox does not contain HID data and
instead works at the top level.

To handle this I made the Joystick object use multiple InHeritence like:
class JoystickController : public USBDriver, public USBHIDInput

This allowed me to have the object work either way.  This did add some
complexity in that some of the methods like  is the object connected
(The bool operator) had to be overwritten as both of the bases classes
had it.  In addition needed to update the other query functions to be
able to grab the data from mydevice or device depending on which type of
controller was connected.

Since this looked like a valid way, I then merged the Keyboard Extras
code that Keyboard and made it also do a similar multiple inheritance.
In this case however I restricted the HID top level report handle code
to only accept it if on the same object that claimed the keyboard.

The mouse test app was updated as well

Needed HID Parser to support Bidirectional Transfers

The HidParser code was setup such that the claim for a report, the caller could say I want to claim the whole thinig and allowed callback functions for processing of in buffer and out buffer.

Allow RawHID to contribute Transfer_t

Since RawHID may need more resources than most, maybe it should contribute the additional structures

The constructor for a RAWHID object allows you to specify the top usage
that it wishes to connect to.  I used this for example to be able to
connect to a Teensy with the RAWHID associated with emulating the
Serial object.

If a HID Input class says that it wants to claim the whole interface, I
reuse the buffer associated with holding the HID descriptor and use it
for output buffers.

I did a quick test using the Serial test app, where I can type in lines like:
#38400,7E1
And it reopens the serial port at the specified baud and format.  Note the formats the test app looks for is 7E1, 7O1, 8N1, 8N2.

Tested on an FTDI, PL2303 and CH341.  I also tested going to Teensy 3.2 CDCACM.  But as far as I know the teensy could not care less about Baud/Format.

Unless of course there is a way to query the value and use it to set a Hardware Serial port to it.
