[PATCH 2/2] usb: Set unused ports to "fixed" rather than "unknown"

From: Matthew Garrett
Date: Wed Apr 08 2015 - 19:36:29 EST


The Microsoft document "Using ACPI to Configure USB Ports on a Computer"
makes it clear that the removable flag will be cleared on ports that are
marked as unused by the firmware. Handle this case to match.
