Burned AMS1117 on Arduino Mega R3

-

hi!
unfortunately burned out power regulator ams1117 (5.0 h345ke).
so placed new ams1117 (5.0 h1314e), , arduino works (on power usb , power supply).
but pc doesn't recognize it, , me important communication...
is it, regulator? or maybe there can burned else?;-/
i hope atmel 16u2 not burned, i'm not sure, , don't know how check it.

did check power @ 16u2? how did happen? maybe burned traces supply power 16u2. 5v or ground.
