I have 12 workstations running a very high-end machining application. The software's license manager detect the presence of USB key with a license number... I would like to be notified by email whenever any of these USB devices are removed or inserted. The workstations are all Windows 7, the security key's are USB Hasplsm running a Sentinel driver. I suspect Powershell is the best option for reporting this. Any thoughts or suggestions?
