Burned IC (Has something to do with USB)
Looks to me like a single gate CMOS tristate buffer, able to run from 5V, such as a 74HCT1G125.

It's job is to turn on the high side P channel MOSFET (Q1) so that the board's VIN (5V) power supply can drive out on the VBUS pin of the USB connector when the USB OTG port is in host mode and supplying power to an external device.

I don't like the lack of a pullup on its A and OE pins. See if you can bridge pin 1 to pin 5 with a 10k resistor when you rework it.

If you don't need host mode you could just remove Q1.

If you only need host mode you could remove Q1 and short across pins 2 and 3 of its footprint. Proceed with caution in this case, you'll release more magic smoke if you connect via a USB device cable.
