Alan Mac Posted October 2, 2015 Share Posted October 2, 2015 I have a Asus Z87-k motherboard and the USB 3.0 only works with 2.0 devices. Dores anyone know how to solve it? Every 3.0 device, That i plug into a 3.0 door, isn't recognized. Link to comment Share on other sites More sharing options...
theconnactic Posted October 2, 2015 Share Posted October 2, 2015 I have a variant of this issue: in my case, all my USB3 ports (Asus Gryphon) are listed as USB2 ports/hubs. If I plug any USB3 device, such as my Samsung M3 portable HD, it will be recognised - but as USB2, with maximum speed of 480mb/s. Any solution for your USB3 might as well solve mine. All the best!
