No i never configured them in the past they just work
Okay. That is what I would expect
Looking at your screengrab from IORegistryExplorer you have all USB ports available. I would expect HS02 to also be SS02 but 16 addresses higher for the Z270 chipset, so 02,00,00,00 and 12,00,00,00 etc, unless MSI has done something unusual. HS08 would be SS08 - 08,00,00,00 & 18,00,00,00 etc.
You say you have configured the Internal ports as "UsbConnector" type 255. So have you created an SSDT for all 26 ports?
