Dead USB Port A not B, mistyped. :/

It is receiving power okay.

Board looks like it may have been water damaged but customer claims it just stopped working.

I have a Boardview but no schematic for this one, so some guidance would be appreciated.

Where should I start?

L4600::pin1 == 0.487
L4600::pin4 == 0.491

L4600::pin2 & Pin 3 == OL.

U4650 looks spotless. The whole board is really clean if it weren't for redish probe points.

I need a part number if possible please.

I can't find a schematic so I'm doing this all off only a boardview.

Thanks for the screen shot.

I took the part from a 3115 board and she booted straight off the USB_A. :)

I'll try mark this post as SOLVED, but maybe a moderator can if they see this.

Thanks to dukefawks too!
