Drivers needed to talk to the Arduino (or compatible) controller on your DIY EDTracker device. These are taken from the 1.6.9 IDE release (Windows 8/10 compatible) available on Arduino's website; they are untouched and should detect your EDTracker as an Arduino Leonardo device. In our experience, most of the Sparkfun Pro Micro clones out there report as an Arduino Leonardo. If these drivers do not work for you, then you need to speak to the vendor who supplied your Sparkfun Pro Micro board (or clone) - try the Sparkfun drivers.
These are no different to what is supplied as part of the Arduino IDE - we have not altered them in any way - it is just easier to download these rather than a whole 120MB+ of IDE !!!
