Hi All,
I’m really confused about the GPU need for USB RemoteFX redirection:
1- I’m sure that for RDSH GPU is not needed for USB redirection (W 2008 R2 SP1)

RemoteFX for RD Session Host server hardware requirements
If you are using RemoteFX on an RD Session Host server, the processor on the RD Session Host server must support Streaming SIMD Extensions 2 (SSE2). The RemoteFX encoder is optional server hardware, and it can be installed for additional scalability on the RemoteFX server. The hardware encoder card must be installed in a PCI Express x4 slot or greater.
2- But for USB RemoteFX redirection for VMs hosted in a RDVH server, the RDVH server must meet the SLAT and GPU requirements (W 2008 R2 SP1)

RemoteFX for RD Virtualization Host server hardware requirements
SLAT-enabled processor The processor in the RemoteFX server must support Second-Level Address Translation (SLAT). In virtualization scenarios, hardware-based SLAT support improves performance. On Intel processors, this is called Extended Page Tables (EPT), and on AMD processors, it is called Nested Page Tables (NPT).
GPU At least one graphics processing unit (GPU) is required on the RemoteFX server. The GPU driver must support DirectX 9.0c and DirectX 10.0. If more than one GPU is installed in the RemoteFX server, the GPUs must be identical. The GPU must have sufficient dedicated video memory that is separate from system memory.
My question is very simple : Do we need GPU and vGPU for RemoteFX USB redirection in the RDVH Windows 2008 R2 SP1 server ?
