I don't understand the nature of the relationship between a motherboard manufacturer and AMD but when I got my MSI Tomahawk board for my Ryzen I really thought I was losing my mind. I would have USB devices stop working at the most random of times and some of them would continually cycle between connected and not connected.

A motherboard update from MSI applied something from AMD and that fixed the issue.

They’ve improved by three decimal orders of magnitude since then. How much more can we ask of them?
