Why are there no USB components within a vWorkspace RDSH role install?
There is no "Quest Software USB Virtual Hub Terminal Server Service" or similar running on the server, nor any drivers or systrays. I'm also missing a folder "USB-IT" in the install directory (C:\Program Files (x86)\Quest Software\vWorkspace) as one might expect there to be.
This is by design.
vWorkspace USB redirection is not supported on RDSH servers due to the shared nature of RDSH servers, you cannot get session isolation. Therefore we do not install USB components within our RDSH role.
The USB components are within PNTools. PNTools is designed to run on single User operating systems such as Windows 7, Windows 8
You can install PNTools on server operating systems if you plan to use the OS as a VDI I.e. a one user to one virtual machine relationship.
There is a way to use USB redirection on RDSH using MS RemoteFX (RDP 8)
