Do you have the latest BIOS for your system ?
Yes, the latest BIOS version is installed.
If I configure USB4/thunderbolt support as module, the timeout does not apply but the error ist the same.
You may need to take this to your board manufacturer. I see the similar errors to yours with nothing but a BIOS update solving it. You could enter a bug on bugzilla.kernel.org and see if the maintainers have better advice. There's also the linux-usb mailing list. https://lore.kernel.org/linux-usb/
Please let us know the bug number if you decide to file this upstream
