Do they have anything to do with the USB controller?
Don't worry. You motherboard is not affected by the Etron problems, because Extreme7 uses ASMedia ASM104 USB 3.0 controllers, which are reliable.

The Z68 Extreme4 Gen3 motherboard uses the famous Etron EJ168A controller.

XFast does more harm than good, so I after a few test I have removed it.
