I'm on Gigabyte GA-Z77X-UD3H.
All my 4 intel USB 3.0 Ports are dead (meaning out of power supply at all) except only when I change the xHCI mode in the BIOS to disabled (meaning USB2 Only).
So I can't install ML using UniBeast USB(2.0) Stick in any xHCI modes(Smart Auto, Auto, Disabled) with the "Still waiting for root device" error.
Of course it's okay for me because I don't have any USB 3.0 + devices
but I'm very curious about the fact that a number of forum users have posted that they have no USB problem on gigabyte z77 boards, typically UD5H.
Are there any significant differences between USB functions of the UD3H and the UD5H?
or Do I need patched DSDT file in my Extra folder where I don't have any dsdt.aml now?
