Had a board come in where my USB breakout board showed VCONN shorting to ground and absolutely nothing showing up on the ammeter when plugged in. Removed port and tested on the pad, but short still remains. The board is able to boot into the OS with a known good battery hooked up, and everything else on the switch is functional.
Could m92 be the culprit here? I did check pin 5 and its corresponding passive and did not see a short to ground on either. Pin 4 and 6 do, however, show shorts to ground. My revision does not seem to have that one diode on the side with PI3, but the empty pads are showing shorts to ground.
