USB 2.0 Ports Don't Work In Fedora 43 KDE Plasma

I installed Fedora 43 KDE Plasma on a system that previously ran EndeavourOS.

With Fedora, the USB 2.0 ports on the I/O backplate I used for the keyboard and mouse with EndeavourOS do not work at the LUKS prompt on Plymouth, on the SDDM login screen, or after the system has booted into the desktop. The USB 3.0 ports do work (that’s how I got to the desktop).

I think I did the installation with the keyboard/mouse plugged into a USB 2.0 port, which would mean the Fedora Live USB would have worked with USB 2.0, but I can’t remember for sure. I have not (yet) tested a Live USB since doing the installation to see if USB 2.0 works, but I can do that if it will help.

An easy workaround is to use the USB 3.0 ports, but I’d like to get the USB 2.0 ports working, if possible, without altering the system such that it’s difficult to maintain and upgrade.

I’m running the latest non-beta version of the BIOS for the motherboard I can find, and didn’t see any settings in the BIOS that would explain USB 2.0 not working with Fedora 43.

Here is the system info:

If it worked from the Live image, then it is probably something that was introduced with a kernel update. You should be able to select your previously installed kernel from the boot menu. Does that work around the problem?

Wow! @glb, I think that’s the fastest response to a Forum post I’ve ever seen!

Thanks for the suggestion. I haven’t confirmed that it worked with the Live image, but I think I found a fix.

In the BIOS settings, there is one called “EHCI Handoff,” which it says, “Enables the support for operating systems without an EHCI hand‑off feature.” It was disabled, so I enabled it and rebooted with the keyboard plugged into a USB 2.0 port, and it worked! I’m typing on it now.

I’m going to disable the EHCI hand-off and double-check that it breaks USB 2.0 support, then post back with my results.

I disabled the “EHCI hand-off” and confirmed that with it disabled, USB 2.0 ports don’t work. I re-enabled it, and the USB 2.0 ports work.

So I was wrong about there not being any settings in the BIOS that could explain USB 2.0 not working in Fedora 43, there just weren’t any settings in the BIOS I understood that would explain USB 2.0 not working in Fedora 43. :slightly_smiling_face:

The journalctl output took a while to sink in. Thanks for responding.
