right USB port - short circuit

A few days ago i plugged in a faulty device into the right USB port of my 2 year old 'Lenovo Thinkpad Yoga'. Afterwards the whole Laptop was without function. After disassambling the back, removing the battery cable and the bios battery, it rebooted but the USB port stayed without funktion.

Is there some kind of circuitbreaker to change or a way to replace the USB port?

best wishes
