Bug Description
This is an Intel-specific feature. When a USB port is powered off, VBUS is
removed, and port events are lost (device connect & disconnect, remote wake
from USB device suspend, and overcurrent events). OEMs may power-gang several
ports together, so VBUS may not be removed until several ports are powered off.
