title: How do I program a driver for a USB device for windows platform?
body: <p>I am looking for a device that reads wiring voltages via a USB interface and returns the data. How would I go about programming something to interpret this data and what language would I use?

  edit:
  If it helps, this project is to develop a digital tachometre for older engines that don't support a comprehensive ODB2 data port. Therefore, it will read voltages on a DC circuit and have an accurate graphical interface. I have absolutely no idea where to start with all this but am determined to make it work! it's for windows.</p>
