As I suspected my bus filter driver stopped working in Windows 7. I used NODE_DEVICE_EXTENSION in QDR… If I understand right in Windows 7 I have to send requests to PDO only after IRP_MN_START. Is there any way to get config rom from newly added PDO in QDR?
WDF introduces Plug and Play state machine but I can’t find clear discriptions of those state changes and what can (or can’t) I do in those states (or interact with “those states”). Can I send a request to some device that has only WdfDevStatePnpInit?
The definition of what can be done in what state is up to the driver using KMDF, not KMDF itself, so you will not find a statement that says in state X you can do Y in KMDF from a client driver loaded on top of the KMDf bus driver

Hi, All!
As I suspected my bus filter driver stopped working in Windows 7. I used NODE_DEVICE_EXTENSION in QDR… If I understand right in Windows 7 I have to send requests to PDO only after IRP_MN_START. Is there any way to get config rom from newly added PDO in QDR?
