scapy did not detect second network as per conf

[houming chew]

I have two interface cards in my pc. Ipconfig are able to show the ip of two cards. But when I use show_interfaces() in scapy, I am not able to view second interfaces.

scapy not able to detect second interface, means I can't sniff packets coming in. Scapy keep using the first interface to sniff.How can I up this second interface?
