Windows Server 2012R2 is now able to redirect USB to terminal services, not only to virtual machines
On my freshly installed system "Device Setup Manager" is "Manual (Trigger Start)". Not "Automatic". And it starts. I don't know which event triggers it, but it does. Perhaps, reinstall the system is a solution? I have no better ideas.
OK. I think I won't be doing that but if I ever need to access the printers properties at least I know what to do. Thanks for all the help. Most importantly it is working.
