I have a windows 2012 RDSH farm setup and working. All works fine except redirecting of scanners. I have other devices using the RemoteFX USB redirection and it works fine for things like HID Input devices but scanners do not.
I have a Ambir DS687 and a Ambir 821i that I am trying to redirect. The scanners connect and the devices are listed in Devices and Printers and show as working. When I try and right click on one of the scanners and go to START SCAN it does nothing. I try to add a profile and it states that it cannot find the scanner. If I use the scanner software which I installed on the session host I can scan but I need this to be available via WIA.
The client machines are windows 7 sp1 and windows 8.1 both with RDP 8.1 protocol and UDP transports open and available. Any help would be appreciated to get WIA to recognize the redirected scanners.
