That sounds a lot like the same hardware failure I have on my
old P8H67-V (AUSTek) system. I just tested it again, and the USB3
ports will work with a single simple device plugged in (like a
USB keyboard, which is what I tried), but a hub, or a device which
actually wants to talk USB3 (like a disk drive) doesn't work.
It worked fine up until I rebooted with a new kernel this afternoon. So if it is a hardware failure, it has worked perfectly since I got the board a year ago and failed after I updated and rebooted this afternoon. Can't say that didn't happen, but it seems really co-incidental.
I'm assuming the southbridge chip (or whatever it is called)
is dead or at least half dead.
X570 is an AMD AM4 motherboard. I'm running a Ryzen 3600X processor. System has been rock solid since I fixed a power supply issue a few months ago.
The USB2 ports do work.
The other hardware failure on this is the onboard Intel video
which I guess must use the same half dead chip.
I have an NVIDIA GTX 1080 Ti video card.
