I thought I read in another thred and on the internet this was a problem with Intel CHip being made to a early release of spec. Not all Mfg of connecting devices were following the same specifications.
That's probably the cause..., but it doesn't help when I boot up and have to switch USB plugs around because some of the ports have stopped working. I thought I had it fixed with an update a while ago, but it's popped back up, and I've had to revert to using an external USB hub again. I also want a board that will run PCIE 3.0. I know that the Classified is not guaranteed to do that..., that it's only certified for 2.0, but others, perhaps most, seem to be able to get it working. I bought it, thinking it would run PCIE 3.0.
I'm looking at a big purchase of a couple of higher resolution monitors, (the old, aging eyeballs like 28 inches at least), and most of the people who have gone to other boards say that they have had much more success than they did with the EVGA X79 boards.
I've bought many items from EVGA and spent a few thousand dollars with them and have been very happy up until now, but they seem to have dropped the ball on the X79 boards. If I could get them to exchange the one I've got for one they could guarantee will run USB 3.0 and PCIE 3.0, I'd gladly do it.
