As we know, Windows OS has a very useful feature called Remote Desktop. It works well with apps, but when it comes to watching a video or playing a video game, chances are you will get just a “slide show”. Also, it’s rather inconvenient that the PDP protocol does not allow redirecting a wide range of locally attached USB devices.
To solve these and many other problems, Calista Technologies has developed the RemoteFX technology.
RemoteFX is a set of protocols used for delivering Windows virtual desktops over LAN. This technology allows RDP USB redirection to guest OSes, which means you can get access to peripherals inserted into your host when working in your virtual machine.
Starting from Windows Server 2012 and higher, RemoteFX offers extended capabilities for USB redirection over RDP. These include:
Probably the biggest difficulty you may face when trying to use RemoteFX is complex configuration it requires. What’s more, you’ll need to make sure that:
As you can see, there are quite a lot of requirements for enabling the RemoteFX USB redirection feature.
On the other hand, there’s an alternative solution that provides remote desktop USB redirection functionality and makes it simple to access local USB devices from a virtual desktop.
USB Redirector by Electronic Team, Inc. is designed to forward devices over RDP in such a way that they appear in a remote system like they were physically attached to that machine. What’s great is that you don’t need to make any complex configuration. Just a couple of clicks is enough to connect to your local USB device from a remote PC.
For now, the native methods of the RDP protocol allow redirecting only devices of certain types. Often, these are printers and USB flash drives. But if you want to forward USB peripherals without any limitations concerning device type, you can opt for USB Redirector like USB Network Gate (UNG).
The software will help you share a physical USB port with your virtual desktop. This means any device inserted into the shared port will become available for remote connection while you are working over RDP. If you unplug one peripheral and plug another one, the latter will be redirected to the remote desktop automatically.
First of all, you need to install the app on both computers that will take part in the connection:
Once done, just follow these simple steps:
So, now when you connect to the Terminal Server over RDP and get access to the locally shared USB device using USB redirection software, the peripheral will appear in the server’s Device Manager and all programs installed on that computer will work with it as though the device were connected to the server directly.
The software edition for Linux supports RemoteFX USB Redirection [MS-RDPEUSB], which means you can forward shared USB devices from a server machine running Linux OS to a Windows client machine.
The client should be either Windows 8 (real or virtual machine) or Hyper-V running Windows 7 SP 1, with the RemoteFX GPU added, launched on Windows Server 2008 R2 SP 1 or Server 2012.
Here’s the command you should execute:
xfreerdp-usb [shared-ports] xfreerdp-args
Where the arguments are:
If you get SSL_read: I/O error, you should add “--rfx” parameter without quotes prior to IP address.
