Yes. I know that I am getting a AddDevice again for the same device. But, I
haven't checked the PDO. I checked by having only two devices of the type in
the system and returning SUCCESS for the first device and
STATUS_NOT_SUPPORTED for the other.
And, I am loading as a driver for the device on top of PCI.sys as a PNP
driver and I hope this means it is a service for the device. Is there a way
to verify this?
