Driver station only regognizes USB 1 and 2

[cvxdes]

So on our bot, we decided to have 4 joysticks. 2 for the driver, in tank mode, and 2 for the person handling the ball mechanism. Driver gets USB1 and USB2, and ball handler gets USB3 and USB4.

I spent hours today trying to figure out why when I go all the way to -1 on the USB3 and 4 joysticks, nothing happened.. Then I just set up the motor VI with a constant of -1, and it ran. Then I hooked up the joystick indicator to a display, and realized that the joystick wasn't talking to the program.

I tried too many things to list in order to get it work. Several reboots, switching around joysticks, and can't find a way around it.

Anybody have any ideas on why it's doing that? I'm pretty much stumped.
