Well, I found out why my old motherboard smelled like fire - Page 2

The circuit definitely could've failed by some sort of overload (i.e. check the USB devices?)... MOSFETs and capacitors across the board, unlike the Mobo VRM, aren't (usually) protected by some sort of OCP, because there's really no need.

The i-charger thing (or what ever the name) may be the issues here.They started pushing BIOS-es for that feature and they forgot the MOSFET capabilities regarding those circuits.As the current limit was removed by the feature you can have this nice burn ,maybe generated by some short in the usb cable.At least this is my theory.
Anyway if it works it s ok
Most mobos have a protection for short or static and so on for the USB.At least MSI was hyping this USB protection things some time ago.

Anyway you can observe such a burn ,when you replace a mobo easily
I would also look for stand offs placements or lack of them.
