I have setup a test envrionment with Server 2012. RDS has been installed. Hyper-V, RDCB, RDWeb, and RDVH are all on the same box. I have a personal unmanaged Remote Desktop Virtual pool with one test virtual running Windows 8. I have enabled RemoteFx USBdirection in Group Policy on every machine involved and forced GP update.
I can see my devices in the Remote Desktop Connection details on the client (i.e. it shows up under Local Resources/Local devices and resources/More/Other supported RemoteFX USB devices. Or, if you prefer, I have added "usbdevicestoredirect:s:*" to the .rdp file that the Web Access spits out then I log in to web page and attempt to connect to my published virtual machine.
The problem is that the devices do not show up anywhere in the virtual machine's device manager once logged in. Furthermore, there is no Universal Serial Bus node in device manager at all. I do not have a RemoteFX compatible GPU available for hyper-v or the virtual machine, but it is my understanding with Server 2012 and Windows 8 this is not necessary.
Does anyone have any ideas? I thought I saw a rfx@microsoft.com or similar email on one of the blog comments, but I can seem to find the post again, I have scoured the internet relating to usb redirection and remotefx and it is a disorganized mess.
Thanks.
