The issue is with the ACPI tables - the USB role switch ACPI device nodes don't have the _PLD object on these systems. Ideally this could be fixed there by simply adding the _PLD to those ACPI device objects, but I understood that that is not an option. But maybe I misunderstood... Can the ACPI tables on these platforms still be updated? thanks, -- heikki
