Thunderbolt gig ethernet adapter

Hey all, I was hoping someone may have a possible solution for an issue I ran into this morning. We have some thunderbolt gig ethernet adapters to use with our MacBook Air's. When you plug this in as a standard user it will recognize the new interface, but will need an administrator to apply the change. This, however, is rather inconvenient. I can use networksetup to create a new service, but this will only work once the adapter is plugged in.

All MacBook Air's (mid 2013) on 10.8.5 with latest updates

Any idea's or suggestions?

Thanks
