I have a Asus Z87-K motherboard and the USB 3.0 only works with 2.0 devices. Does anyone know how to solve it?

Every 3.0 device, that I plug into a 3.0 door, isn´t recognized.

I have Z87-A and also have problems with my USB 3.0 ports. My USB 3.0 external drive has to be connected to USB 2.0 to work, but USB 2.0 devices work fine in the 3.0 ports. This is the only issue I have with El Capitan as of now.

Same issue here on GA-Z87MX. USB3.0 external drive is not recognized on USB3.0 ports but is recognized on USB2.0 ports. USB2.0 devices are recognized on all ports: USB2 and 3.
