Left/Right on D-Pad Joystick Axis, Axis 6

Up/Down on D-Pad Joystick Axis, Axis 7

Left Trigger and Right Trigger both correspond to joystick axis, axis 3

in case anyone comes here looking for more button mappings for the xbox 360 controller, here's what worked for me (using the tattie-bogle driver for osx):

D-pad up: joystick button 5
D-pad down: joystick button 6
D-pad left: joystick button 7
D-pad right: joystick button 8
start: joystick button 9
back: joystick button 10
left stick(click): joystick button 11
right stick(click): joystick button 12
left bumper: joystick button 13
right bumper: joystick button 14
center("x") button: joystick button 15
A: joystick button 16
B: joystick button 17
X: joystick button 18
Y: joystick button 19

The triggers are not buttons, they are additional analog joystick axes, either 6th and 7th, or 7th and 8th. However they operate between 0-1 instead of -1 to 1.

The home button, I am not sure about, it may be a special mapped button and not accessible.

Also, are you on a Mac, or PC? On a mac, using the open source library, the mappings may be different, as well. I haven't tested the PC bindings, so I am not sure - Tattie Bogle OSX 360 controller driver

i've been trying to map my xbox 360 controller to my unity project (on a mac) and am using tattie bogle's driver as well. thanks to gyro (and a few other sources) help, i think i got it. i made a visual, for anyone else that needs it. if you see an error in here, let me know.
