From 58339c2e8b6181e6ffb2ef0dccc4d010b8acd013 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Wed, 8 Apr 2015 16:36:01 -0700 Subject: [PATCH] usb: Set unused ports to "fixed" rather than "unknown" 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.
