Turns out they are a lot different than other PS3 controllers.

When plugged into USB, it appears like these units do not send
any reports.  They do allow us to do pairing (which is differnt)
than other PS3, as well as set the Bulb LED color, which I now
have it alternating colors every few seconds and also it tries
to pair it with a BT dongle

When connected to Bluetooth, it now is setup to generate reports,
as well as again set the bulb color and rumble.

So far it maps the 3 button bytes into the buttons field and then
simply copies most all of the data down into Axis, starting where
the Trigger button is.

JoystickBT.ino was updated, to know about this controller and as
mentioned above in the USB case it tries to pair and plays with the
color of bulb.

In the BT case it tries to display data.  I did a quick and dirty
change of the Accel/Gyro like stuff which is probably totally wrong.

Pressing some of the buttons will set bulb color and pressing trigger
will set rumble.

PS3 Motion controller - very little mapping of axis
