Needs it? Probably not. But if you have a Windows PC connected, open a command prompt window (Start, Run, CMD, Ok) and type:
ipconfig /full
that will tell you everything it knows about the network. If the PC can connect without needing a "client ID", then the USB adapter can. However, most colleges require registering a computer's MAC address with the network admins, so if the kiddo isn't using a router, then you'll need to register the adapter's MAC. You probably should have a router set to mirror the PC's MAC and then you won't have a problem.
