GIGABYTE has just kindly let us know about a firmware update for the NEC USB 3.0 controller found on many of its latest motherboards. The update is primarily for the purposes of improving USB 3.0 device compatibility.
The new firmware is inclusive of an executable update tool which you simply run from within Windows to have your controller updated to the latest. Please note; this Update Tool is only suited to Windows 7 and Vista.
If you have one of these boards from GIGABYTE, then you have NEC's USB 3.0 controller which can be updated with the use of this firmware update tool :-
I would presume this firmware update tool is also fine to use on other manufacturers boards running NEC's USB 3.0 controller, or any standalone PCI-E cards with the chip for that matter.
