Besides previously announced RemoteFX and Dynamic Memory feature which’ll come in SP1 Windows Server 2008 R2, and will greatly improve VDI scenarios, Microsoft announced a new RemoteFX feature specific for VDI on Hyper-V “Generic USB redirection,” which allows you to redirect virtually any USB device transparently over RDP. Support for more devices than previously. Support for USB devices with thin clients. No client drivers necessary. Applications are transparent to redirected devices. Only one session can use USB device at a time. So Webcams, headset, Windows Mobile devices Printers, scanners work great!
