NDIS PASS THROUGH SAMPLE BUG

Hi,
First I installed a regular NIC card on my machine, After that
I installed windows pass through IM driver. Everything is fine.
I go to ControlPanel->System->Hardware->DeviceManager->NetworkAdapters
and I see all the Miniport Pass through Adapters for each real NIC card.

Now I install the USB NIC card, installtion seems to be going fine.
Now I go and check the NetworkAdapters but now I dont see any Miniport
Adapters corresponding to each Real NIC card.

Can anyone help me in this.

thanks,
Hari.
