Essentially this means that the Device Manager depends on the (static) INF

I wish there was a way for the Device Manager to obtain the device names
directly from the driver rather than rely solely on the INF files.
I mean bus drivers do provide names that appear in the new hardware found
wizard (in response to (IRP_MN_QUERY_DEVICE_TEXT?).
But then, there are times (say on a PCI bus) when bus drivers have no way of
telling the actual device name!
I guess there is no simple solution.
Thanks.
Devendra.
