beads said: You can only disable USB ports while running a Linux guest (externally) from VMWare Workstation Pro not from Viewer. You would have to disable USB ports in Windows by way of the registry settings internally no matter which version of Workstation. Not entirely sure if you could do so from the EXsi master or not as I haven't had a need to do so.I am sure if you searched the VMWare docs its there somewhere.- b/eads
