Hi All,

just wondering where my mysterious Vcc voltage might be coming from. I'm using a teensy 2.0 board, and am cutting the trace on the bottom of the board that connects the 3v and 5v pad so that when plugged into USB, the Teensy does not get powered. Oddly enough though, I'm finding a small voltage on my Vcc with this setup, ranging between 0.3-0.4V. From everything I can see in the Teensy 2.0 schematic, I don't see why this would be happening... Any ideas? Thanks.
