RE: [Q] What does DRVO_LEGACY_DRIVER mean?

If you do not create a device object during AddDevice, this flag will get
set so that the driver does not unload.

> Hello,

> Perhaps this also explains why my driver doesn't seem to get sensible

> SystemPowerUnspecified, regardless of whether the system is suspending,
> resuming or powering-off. Does this have anything to do with the
> DRVO_LEGACY_DRIVER flag being set?
> Thanks for any help.
