I can't seem to tell if the Raspberry Pi Zero's female micro USB port is and/or requires USB OTG. I see a lot of people talking about USB OTG on the Zero, but the specs I've seen don't mention USB OTG, just USB.
Therefore, do you need a USB OTG cable, or can a simple physical adapter be used in conjunction with the Pi Zero?
Edit
The wiki page is the best way to read up on USB OTG and what makes it different from USB.
