NX_SUBTYPE_AUX_CONTROL_BUTTONS usage The incoming NXEvent for other mouse button down/up has event.type NX_SYSDEFINED and event.data.compound.subtype NX_SUBTYPE_AUX_MOUSE_BUTTONS. Within the event.data.compound.misc.L[0] contains bits for all the buttons that have changed state, and event.data.compound.misc.L[1] contains the current button state as a bitmask, with 1 representing down, and 0 representing up. Bit 0 is the left button, bit one is the right button, bit 2 is the center button and so forth.
