I think there is a detection switch that shuts down the USB port? I need to identify it/

I found that UI3 chip (Usb Detection controller switch)

gets too hot immediately after powering the motherboard. 

I don't know if it is faulty or something else cause it to be hot.

Now I removed a shorted capacitor. The chip doesn't get hot and I get 5 v from usb port.

I haven't found a replacement yet. I am not sure if this would cause any damage.
