FNO: FrameNumberOverflow: Disable interrupt generation due
to Frame Number Overflow.
RHSC: RootHubStatusChange: Disable interrupt generation due
to Ownership Change.
OC: OwnershipChange. Enable interrupt generation due to
Ownership Change.
MIE: Master Interrupt Enable: A zero written to this field is
ignored by HC. A one written to this field disables interrupt
generation due to events specified in the other bits of this
register. This field is set after a hardware or software reset.
