Hi, I have just upgraded to Mountain Lion from Lion. USB 3.0 worked fine on Lion but since upgrading none of the USB 3.0 ports work at all in USB 2.0 mode or USB 3.0 Mode. The devices i.e. USB 3.0 drives are powered up but are not recognised in Mountain Lion. I have a Gigabyte Z68MX-UD2H-B3 v1.3 F13.
Thanks
Thanks
