unipolar stepper motor program

[odphuthego]

i have to write a c++ program that should be able to drive a unipolar stepper motor but through an open usb in full mode, you have to read the status of the motor and then move a few steps either clockwise or anticlockwise.

if you enter a +integer, you have to move integer number of steps clockwise and viceversa if its -integer.

anyone have an idea??
