Er... Have you connected your device to a hub, a switch or a router? In turn connected to another devices, a LAN, Internet, or what?

If I understand you well, you are connecting your device to a switch, and then you are trying to monitor with it the traffic that goes between the other ports of the switch, right? That will not work: a switch filters the traffic, and only delivers to your device the layer 2 traffic that is directed to it, including layer 2 broadcast traffic. If you want to monitor all the traffic, you need to use a hub (which is "layer 1 device"), or use a switch that can be configured to deliver all the traffic to one specific port.
