Is there an updated version for the latest softwear for the enterprise 3d mouse?
I found this forums post but its an older version of the software
3DConnexion SpaceMouse settings for MicroStation. - MicroStation Forum - MicroStation - Bentley Communities
I am not aware of any updated driver for the 3DConnexion.
The extra buttons on the mouse should be recognized as xbuttons:

Once you know which button corresponds to each you should be able to assign tools/commands to each button.
