You suggested to remove the port field and to ignore the slot number for root ports, and I understand the reasoning, but, from safety reasons, if we know that device 2030 will always be found on slot 0 and 2032 for example will always be found on slot 2 wouldn't it be prudent to compare the device number vs the port number, unless you believe that the BIOS/ACPI issue will be fixed. Shlomo.
