PS3 - Right Joystick does not work

There is an issue with the extra items added to the report after the main known items.

Problem was HID report descriptor does something like:
Usage Page; Desktop  (01)
Usage: 01  (Pointer)
Count xxx

Problem is the Usage values below 0x20 appear to have some other standard meaning.   Which you can see in
http://www.usb.org/developers/hidpage/Hut1_12v2.pdf

So current fix is to ignore Usage values passed in < 0x20...
