Asus AC56u USB port broken?

[smnrock]

Apologies for creating duplicate thread, but the previous one was created in wrong location... I hope this thread gets more visibility!

Suddenly USB ports in my AC56u was stopped working which was running merlin firmware. Then i tried with original asus firmware and other firmwares as well, but without any luck. Now im back to latest merlin firmware, but still the problem exists. The log says, over current in usb port.

Any help? Or its a hardware issue?
