The advice about using a hub with a metal case is good advice. And absolutely a powered hub. If you stick with certain brands you are less likely to encounter the odd dodgey problem like ports disappearing. Belkin and Startech are names I would trust. Asus and Logitech as well. And you should probably only bother with a USB 3 hub, and make sure it connects to a USB 3 port on the host PC. I have two different hubs on different host systems.One has buttons for each port to turn it on or off. The other that I use for rig does not have buttons. I didn't see a need for buttons on that host.
If the problem persists, it could well be a driver issue for the USB adapter on the motherboard. Not all motherboards are made the same. It might be worth the time to look for an unpublished driver update for the USB controller on the motherboard. Just because Windows Updates doesn't offer a driver update doesn't mean that a newer driver isn't on the manufacturer's site.
