Are you talking about the trigger and top buttons?

If so, they're recognized by the port of the joystick which they're on. For example if you wanted to use the trigger button on the joystick plugged into port 1, you use p1_sw_trig , likewise the top button would be p1_sw_top .

Let me know if this helps.

EDIT: Whoops, I misread your post, you said auxiliary. Use p1_sw_aux or p1_sw_aux2 [just change the number of the port to the one you need].
