So I have a asus A88-x pro and 2 of the 4 rear usb 3.0 ports are not functioning. When I plug something into them it receives no power. My case has 2 usb 3.0 ports on the front panel and those aren't working either. But all the 2.0 ports are working fine even the ones on the front panel and 2 of the rear 3.0 ports are working fine. I've already checked in the bios to make sure all the ports are enabled. So my question is whats wrong with my ports?
