Thanks mostly to Mike (@mjs513) - a WIP to support some of the digitizer tablets that are not properly supported by Mouse.

Like Wacom Intous...

Support to pair PS3 if it knows the BTADDR and user presses select and PS button and plugged in USB.

Remembers remote name, and tries to get it when PAIR version of code is running.  (Currently fails).

Does some mapping of PS3 Bluetooth data to match USB HID data.

Warning: as part of debuggigng why joystickType value was changing, I changed the class to make it a function you call instead of just a member variable.  Should mark it inline...  I think I caught all of the places in example code that was accessing it.  If we find we want ability for user probram to update it, should add another member to explicityly set it.

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.

With this update, I can now talk to the keyboard without having to repair each time.

Still WIP

Code is still WIP, needs lots of reorg and fix up and lots more to figure out.

But started working toward the Bluetooth HID devices and have the messages going back and forth from my BT dongle to a small BT keyboard.
It is finally showing keys being pressed and the like.

Code needs lots of work.  Like does pairing everytime, need to make that optional.

Also need to figure out where to split off the HID stuff from Root BT stuff.  ...

Plus it mainly prints lots of debug information.

WIP - So far i am getting the basic values for 1 XBox 360 controller.  The device should handle up to 4 devices, but so far hard coded to only handle 1...

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.

instead of having each HUB have 7 buffers, which can eat up space.  We have each main object contribute currently one string buffer, which than when we initialize a Device_t we try to allocate one for it, likewise we release it when the Device is released.

Hopefully less memory needed.

Also updated such that the HIDInput classes can not retrieve these strings.

Changed test program to now also have list of HIDInput objects and when I detect a new one, I again print out info on it...

Added the ability to query the
Manufactur, product name and serial number strings from a device.

WIP - Eats up lots of memory, next up experiment move from Device_t object to maybe top level objects.  Probably fewer than them as each hub allocates something like 7 Device objects

I was wondering which drivers were in use, so now print when they are connected or disconnected

I updated the keyboard extras to detect if the report ID is 0xff00 and if so ignore it in the Mouse extras process code.  This helped not handling a lot of extra messages generated by MS keyboard.

Also updated Test app to show names of some of these special keys.

This delta, adds an extra keyboard object to handle those keys that are not part of the main keyboard class.  In particular there are separate HID reports for some of the keys, such as Power keys, and multimedia keys.

These reports might be on separate Interface or in cases where the mouse and keyboard are on the same device, the extra reports may be on the Mouse Interface.

So far I have not tried to combine with Keyboard object as might require multiple inheritance which I would like to avoid.

Also I extended the special key mapping table to map several other keys like F1-12, Arrow, Home/end... To special values where the 0x80 bit is set.  I used the same values as used for the Arduino Keyboard library.  I did not use their defines as they used defines like KEY_F1, which already exists in core, but in core it is the scan code from the keyboard and not the end user value.

Had to increase size of HID report to 512.
Allow HAT to work 10039

Mouse Example prints out Z, Rz, Ry, Rx and Hat values
