Look in the dmesg output from when the hm2 driver loads. It will tell
you which pin number the stepgen dir is on. You can then invert it
with the corresponding GPIO pin parameter.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
