Q. Can I use the RemoteFX USB redirection capability without using the RemoteFX Virtual GPU capability for my VDI environment?

A. In Windows Server 2008 R2 SP1, the RemoteFX USB redirection capability is tied to the RemtoteFX vGPU capability, which means you can't have USB redirection without also enabling the full RemoteFX server-side graphics rendering. These technologies may be decoupled in the future, but there are no firm plans or commitments.
