This year we were only able to use usb-hid joysticks attached to the DS, (as well as the 8 io and 4 analog). but my team would like to make our own pseudo joystick, using a microcontroller like an arduino. Would a usb-serial device (an FTDI chip) be able to be used on the driver station?

or would i have to do something like AvrUsb on the mcu?
