Security Suite, Connection Control Manager, run commands on insertion. It'll take some hacking though, because that's designed to run an alert and continue blocking, while you need it to run a scan and then stop blocking. There's more than one way to do that, best one depends on the time and skills available. However, it would be out-of-the-box simple to enable the device for read-only or encrypted-write only.
Thanks for the feedback. This is a great enhancement request to make it an option in connection control manager to initiate a LANDesk AV scan upon insertion.
