This bit is set when the HC detects that a device on USB is asserting
resume signaling. This is the transition from no resume signaling to
resume signaling causing this bit to be set. This bit is not set when
HCD sets the UsbResume state.
This bit is set by the HC at each start of a frame and after the update of
HccaFrameNumber. The HC also generates a SOF token at the same
time.
This bit is set immediately after the HC writes HcDoneHead to
HccaDoneHead. Further updates of the HccaDoneHead will not occur
until this bit is cleared. HCD should only clear this bit after it saves the
content of HccaDoneHead.
This bit is set when the USB schedule for the current Frame overruns
and after the update of HccaFrameNumber. A scheduling overrun will
also cause the SchedulingOverrunCount of HcCommandStatus to be
incremented.
