Yes. USB device works after adding that parameter to kernel 7.1.5

It's a headless server. The USB ports are rarely used;
thus it takes a long time for me to notice.
Other people encountered this issue:
https://discussion.fedoraproject.org/t/usb-2-0-ports-dont-work-in-fedora-43-kde-plasma/188113
https://darkranger.no-ip.org/content/rhel-9-usb-%E5%A4%B1%E6%95%88%E5%95%8F%E9%A1%8C
However, their methods do not work for me.
Toggling "Legacy USB Support" does not help,
and there is no "EHCI Handoff" option in the BIOS settings
