Never use it. I guess NI-usb6008 should be giving you digital i/o and analog input ports to the computer. For stepper driver, normally it need few digital input to enable the coils, control run/brake, cw/ccw and some other control lines. Besides, to step the motor, you need to provide pulses to the driver and the frequency of pulses is the stepping frequency. So if NI-usb6008 can give pulses at desired frequency, there should have no problem to control a stepper driver and motor.
