Power Control

The module's SUS_S3# signal controls the main power supplies: ATX PSU or on-board voltage regulators.
The signal SUS_S3# goes high when the system enters a Powered-On / Working power state (S0) and goes low during Suspend / Sleep (S3/S4)
or Soft Off (S5).
The module's RSMRST_OUT# signal controls power for all USB ports. This prevents backpowering from USB devices to the chipset on the
module.
