As a self reply, but some one may be interested …
There is a bit that, if you check the PCI PDO, is set for a bus enumerated
PDO. It is DO_BUS_ENUMERATED_DEVICE, of all things. How logical. 
I also
believe that you might use DO_DEVICE_HAS_NAME, since, at least in my PDO
creation, I pass FILE_AUTOGENERATED_DEVICE_NAME to IoCreateDevice. This
research also pointed out that I had an oops since I was not setting the
DO_BUS_ENUMERATED_DEVICE for my PDOs.
Walter, as a curiosity, how do you chase down the FDO/PDO nodes? Using these
flags or some variant? If you covered it in the book … sorry … I’ll get
off my lazy ass and go back and re-read that section.

Subject: [NTDEV] Is it a PDO or an FDO
I have a device object. How can I tell if it is a PDO or an
FDO?
