```

## Discussion

Discussion Indicates device is in a low power state. May be bitwis-OR'd together with kIOPMDeviceUsable flag, to indicate the device is still usable. A device with a capability of kIOPMLowPower may: Require either 0 or kIOPMPowerOn from its power parent Offer either kIOPMLowPower, kIOPMPowerOn, or 0 (no power at all) to its power plane children. Useful only as a Capability, although USB drivers should consult USB family documentation for other valid circumstances to use the kIOPMLowPower bit.
