I tried IoGetDeviceProperty, but I don’t know which parameters I have to set
to retrieve the InstanceId.

From the registry,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\Vid_XXX&Pid_YYY\1234567
8

I would like to retrieve “12345678” string.

Regards

Christian

Yes, unfortunately, IoGetDeviceProperty has no function code for instance
ID, only for hardware and compatible IDs.

Then sending your own MN_QUERY_ID IRP (as Mark said) is a way to go.

I called IoSetCompletionRoutine when the PnP Manager sends a IRP_MN_QUERY_ID
to my filter driver. But i didn’t receive any IRP_MN_QUERY_ID IRP. Do I
have to initialize a IRP from my filter driver in order to retrieve the
InstanceId?

Christian

Yes. Query ID is sent when the PDO is being enumerated, far before your
filter is being loaded. You have to send this irp yourself.
