Some of the external USB devices has internal USB hub, which
make them look like "fixed" rather than "removable". And USB
autosuspend does not work with some of these devices resulting
in inoperable pointing device.
Now the code detect these false "fixed" devices by looking at their
parents. If any of their parent is "removable", then USB autosuspend
is not enabled for that device, which keeps the pointing device
functional.
