Playstation DualShock 4 Controller Notes:
================================================================================ ===============================================
The DualShock 4 controller driver enables rumble and sixaxis support. It also increases compatibility of some games over the official driver.
DS4 sixaxis sensors were about 4 times more sensitive than DS3s. I had to reduce it's sensitivity to make PS3 games compatible with the sixaxis.
DS4 controller PID/VIDs are not hardcoded. You will need to have them in xpad_devices.txt. This gives the option to switch between official/unofficial driver when using the xpad plugin.

Bluetooth Adapter Notes:
================================================================================ ===============================================
The driver is based on the USB host shield for Arduino. It should work for most generic adapters although I have only tested with one adapter.
A maximum of 4 controllers may be connected to a single adapter at a time.
To connect a DualShock 4 controller, first we need to set the internal bluetooth address of the controller.
You only need to do this the first time you connect the controller to the bluetooth adapter.
