Have you tried booting an earlier kernel?Yes. The behavior was consistent across the 3 kernels I had installed. uname -a Linux bigboy 5.10.11-200.fc33.x86_64 #1 SMP Wed Jan 27 20:21:22 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
If it's not working now on a kernel version that did work before, that suggests that it's more likely to be a hardware issue than a kernel issue.
Does anything show up in the journal when you plug something into the ports that aren't working?
Since it appears to be USB3 ports that aren't working, try adding "blacklist=xhci_hcd" to the kernel command line before booting and see if that makes any difference. I don't know if that will do anything since Fedora has that kernel driver compiled in, it's not a module. So if it doesn't work, try "initcall_blacklist=xhci_init_driver" instead. _______________________________________________
I'll test this tomorrow.
