Double USB concept can be plugged in either way

How many times have you tried to put a flash drive into your computer and put it in the wrong way? You always think, why can�t they just go in either way you put it in the port? Ma Yi Xuan latched onto that thought and made the perfect USB plug. You will never again try to jam your USB into anything the wrong way ever again.

An internal spring flips the fixed contact for the transfer of data inside the metal part of the USB, so you can literally never be wrong. Hopefully this will be popular enough so that all USB plugs will be made this way in the future.
