Answer 1

You can enumerate all the network interfaces on your local machine with

System.Net.NetworkInformation.GetAllNetworkInterfaces()

This may give you enough information to determine if the network adapter has been attached.

Answer 2

I think that you should take a look at WMI events. If system broadcast information about hardware being connected, it will do it through WMI
