I have all my controllers plugged into a powered USB hub, and that hub plugged into a USB 3.1 slot on the mother board. That worked fine with my old mother board, however here, it could not properly detect the MFG Crosswinds, so the computer was installing, uninstalling, reinstalling, uninstalling, reinstalling, again and again in an endless loop.
DCS hit that and got completely stuck on there being an indeterminate number of USB devices attached to the system. I moved the Crosswinds to the front case USB 3.0 slot and it all works fine now.
(Sounds of a head gently rapping against a desk...)
