Thank you for your time and answer!Okay. Your English is fine.
With Big Sur running on a mixed controller - XHCI and EHCI - we have to remember no Mac ever had this setup, so there is no built-in code for it.
OS X expects the EHCI controllers to be called EH01 and EH02 and that is why we have the renames, however I have seen this crash Big Sur. Tested and tested. It's true. Maybe not for all chipsets ...
USBInjectAll.kext works with Big Sur but the XhciPortLimit can cause a lock-up since 11.3 which is why a USB kext is needed.
USBPorts.kext does include power settings, which I haven't seen in USBMap.kext.
It might be the case that renaming your EHCI controller on such a "veteran" CPU running Big Sur is a push too far. @RehabMan wrote the guide for USB power delivery but it is not an easy ride.
Sorry I don't have an instant answer to your problem, it is quite rare.
You are probably right about this "veteran" CPU, maybe its time for pension
I shall have a look at RehabMans guide again, even if it is a big bite.
In case I should find something I will write back.
Have a nice weekend, soon
