Problem With Registering PNP notification for GUID_DEVCLASS_NETTRANS

NTDEV
1

Hii All…

I am facing some problem on registering PNP notification for GUID_DEVCLASS_NETTRANS. I registered the notification but I am not receiving any notification ie the callback routine is not getting called. I am expecting the callback routine gets called when \Device\tcp gets loaded. Following code shows how I register the notification.

status = IoRegisterPlugPlayNotification (
EventCategoryDeviceInterfaceChange,
PNPNOTIFY_DEVICE_INTERFACE_INCLUDE_EXISTING_INTERFACES,
(PVOID)&GUID_DEVCLASS_NETTRANS,
DriverObject,
(PDRIVER_NOTIFICATION_CALLBACK_ROUTINE)
CallBack_PnpNotifyInterfaceChange,
(PVOID)deviceData,
&deviceData->NotificationHandle);

if (!NT_SUCCESS(status)) {
DbgPrint(“RegisterPnPNotifiction failed: %x\n”, status);
return status;
}

Can anybody help to resolve this issue.

Thanks

You using a device class guid. IoRegisterPlugPlayNotification works with device interface guids. Furthermore, device interfaces require pnp stacks. The tcp driver is not a pnp driver, so I don’t think there is a device interface guid that will tell you when networking components (outside of NICs themselves) are loaded.

Register with TDI if you want to know when \Device\TCP becomes available as
a network ‘transport’.

TdiRegisterPnPHandlers() is the routine you should look at.

Good Luck,
