I've had this motherboard for about a year, always had issues with the 3.0 ports but just now getting around to solving the problem. The 2 rear ports do not work at all; I either receive no alert and no drive icon when I plug in my external 3.0 HDD or I get a tooltip popping up that says the device has malfunctioned.
The two front 3.0 ports function solely as 2.0 ports as whenever I plug in my 3.0 eHDD I get the tooltip that this device can perform faster if plugged in to a 3.0 port.
I've visited the Gigabyte driver page and attempted re-installing the Intel USB 3.0 Driver. I am not certain of the revision of my MB, however the driver for both revisions on the website have the same version number (220.127.116.11) so I don't think this would make a difference. Device manager does not offer any updates to the installed drivers (which was a solution I've found mentioned in a few other threads).
I've only recently go a 3.0 device to use which is why I am just now trying to fix this issue. Any help would be much appreciated.
