Non-ChromeOS platforms do not have this issue.

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,
