Mac – Connect VirtualBox to a different internet connection

ethernetnetwork-adapterusb-network-adaptervirtual machinevirtualbox

At the moment, I have my host machine setup to access the internet using the main ethernet connection via a NIC.

I have a VM which currently has it's network settings set to NAT, this allows the guest machine to connect to the internet using the same connection as the host machine.

I have a usb internet connection. If the host machine has both the ethernet connection and usb internet connection attached, how do I set things up so the host machine uses the ethernet connection to gain access to the internet and the guest machine uses the usb connection to gain access to the internet?

Host machine = Windows XP
Guest machine = Ubuntu 10.04

These are the 2 connections I currently have:

From these 2 connections, the wireless connection is my main host pc connection which at the moment both host and guest machines use. I want to continue using the wireless connection on the host pc, but on the virtual machine guest pc, I want to use the wired connection 2. The wired conneciton 2 is the usb connection.

What I don't understand is what am I supposed to do on the following screen in virtualbox to select the wired connection 2?:

Change the VM's network interface to bridge mode. This will allow you to select which network interface you want to use.
