Ok cool.

I did a little more looking, and I stand corrected on my previous assumption:

Please note that the power available through the USB ports, digital I/O, and analog input pins is limited to 2 amps total. Care must be taken to ensure that any team-provided devices connected to these sources do not over tax the available Driver Station supplied power.
Seeing as your joysticks will be drawing some power as well, I'd say you'd be safe with 1700mA. But yes, I would suggest ganging several of the power connectors if you're going to be drawing that kind of current. Just to be safe

Note, however, that the wall wart supplied in the KoP is only rated for 1000mA, so you'll have to make other arrangements to supply the needed power while developing the system.
