BTN_DPAD_*
Analog buttons are reported as:
ABS_HAT0X and ABS_HAT0Y
+ (for ABS values negative is left/up, positive is right/down)
Analog-Sticks:
The left analog-stick is reported as ABS_X, ABS_Y. The right analog stick is
reported as ABS_RX, ABS_RY. Zero, one or two sticks may be present.
If analog-sticks provide digital buttons, they are mapped accordingly as
BTN_THUMBL (first/left) and BTN_THUMBR (second/right).
+ (for ABS values negative is left/up, positive is right/down)
Triggers:
Trigger buttons can be available as digital or analog buttons or both. User-
ABS_HAT2X (right/ZR) and BTN_TL2 or ABS_HAT2Y (left/ZL).
If only one trigger-button combination is present (upper+lower), they are
reported as "right" triggers (BTN_TR/ABS_HAT1X).
+ (ABS trigger values start at 0, pressure is reported as positive values)
Menu-Pad:
Menu buttons are always digital and are mapped according to their location
