I've gotten one of my devices returned back to me as being defective. I opened it and noticed the voltage regulator that brings the USB +5v down to 3.3v was overheating. It turns out that there was a short circuit across the voltage regulator. (see pic below)
Does anyone have any idea of what a short circuit there implies? Is it possibly a defective regulator? Does this indicate of particular type of failure? I'm attaching a snippet of of the schematic and the board. I would love to hear any experience with this kind of failure. Thank you in advance for taking the time to help.

Rob
