yes, use the UBS chicklet (link above). we used it last year, and we plan on using it again this year!
you can either use both joysticks and 4 buttons, one joystick and more buttons, or.....well, just read the manual. it explains everything. just remember that at the competition it has to be powered by a separate battery. the best way is to buy another backup battery and splice on a pluggy thingy to power it.
