I am sure there is some really good reason. It just completely escapes me
given that I can call IoGetDeviceProperty() on the PDO which I just gave to
WdfDeviceMiniportCreate(). It surely is not a mystery to the WDFDEVICE what
the PDO is…
And yes, I did go back and read the short list of WdfDeviceXxx() functions
that are supported on miniport WDFDEVICE objects and yes, that is not in
them. I know. Sucks for me 
Of course I will just use IoGetDeviceProperty() and I will not bitch about
it 
- I just was wondering why my trend towards laziness and reliance
on others (Doron, PeterW, etc.) was abruptly cut off with a bugcheck when I
thought ‘how nice, WdfDeviceAllocAndQueryProperty() will handle getting that
string for me…’ - NOT!

Off thwe top of my head, no good reason why this should not work. I can look at the src in a couple of hours with a more definitive answer

Thanks. Obviously not to assist in my current projects but perhaps only to
either further educate me (always a good idea) or to catalog as a possible
‘enhancement’ request for the mythical next release
Cheers,
