Can you not just create the asset?
Note Docking Stations / Thunderbolt etc do not report anything to Windows usable by Lansweeper. I have looked heaps including contacting Toshiba in our case and they have advised there is no way to query the serial number of the dock.
Peripherals are the same. Under the asset, there is an option for Keyboard and Mouse. Doesn't really report anything useful. You would have to add these as manual assets as well. Note it will increase your asset count as well.
I am doing some research and have not found a good method for tracking docking stations, mouse and keyboards, etc. For example, headsets, I have been manually adding them to the user and I am not sure if I can run a report on this or not. I am thinking I would have to manually add docks, m&k combo.
Thanks for all the help and recommendations
