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. I'm assuming the southbridge chip (or whatever it is called) is dead or at least half dead. 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. It can still limp along as long as I don't try to use the stuff that doesn't work, so it is an emergency backup system with a mirror of my main system so I can use it if my main system dies. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
