How do you repair usb controller?

crwdns2934249:0crwdne2934249:0:

I bought a motherboard that works mostly except that the usb ports don’t work. I’ve tried plugging in a mouse to the ports and the mouse does not work. When I plug it into the port not attached to the motherboard, I get a power surge.

Is there any way to find the chip that controls the usb ports and replace it with a chip from another board?
