Right, ACPI spec. doesn't prohibit the use of _UPC, _PLD, but it is not define the _PLD hidden/invisible lane as well. firmware implemented with all unused USB _PLD set to 0, it does cause kernel Warnings and have been discussed with Linux kernel upstream maintainer. /bugs.launchpad .net/fwts/ +bug/2055855 /lists. ubuntu. com/archives/ fwts-devel/ 2024-March/ 013842. html
