What is the utility of this diode? Is reverse current a problem? It's not really hurting anything, but it it's an extra component we may not need.

@Tsillen, do you have an opinion on this? screen shot 2014-12-12 at 11 12 13

This Diode is necessary to prevent the current flow back to USB input and protect your computer USB port. I recommend to keep it in the circuit.

Cool. Let's keep it then.
