Does USB redirection work with a View Windows Client connecting to an RDS Pool running Server 2012 R2

I have installed the Horizon View Agent (6.0.0) and View Direct Connection Plugin (6.0.0) on a physical server running Windows Server 2012 R2 with Remote Desktop Services enabled.  I would like to use USB redirection from the client to the server.   When I log into the remote desktop session using the Windows View client,  it tells me that USB redirection is disabled.   I have tried connecting the View Client to the View Connection server and directly to the RDS server with the same result.  Do I need to enable RemoteFX on the Windows Server running RDS for USB redirection to work ?  I don't have any RemoteFX hardware, that is why I haven't tried it yet.
