As pointed out by Philip Ries [MSFT] here some time
ago, the meaning of SPDRP_ADDRESS / CM_DRP_ADDRESS
is the port number for USB devices.
(http://groups.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/18908b4625564088)

Now I've got my first USB 3.0 Controller card
(NEC �PD720200). For USB devices attached to it,
SPDRP_ADDRESS / CM_DRP_ADDRESS returns 0.

Is this something new for USB 3.0 or a bug in their
driver? I'm using the lates one I've found which is
V1.0.18.0.

this is a bug in NEC's drivers, they are not responding to the right pnp irp
or fillin in the right property

Thanks. Maybe this should become part of the WHQL tests
for USB host controller drivers...
