As a special feature additional to the VRDP support, Oracle VM VirtualBox also supports remote USB devices over the wire. That is, an Oracle VM VirtualBox guest that runs on one computer can access the USB devices of the remote computer on which the VRDP data is being displayed the same way as USB devices that are connected to the actual host. This enables running of virtual machines on an Oracle VM VirtualBox host that acts as a server, where a client can connect from elsewhere that needs only a network adapter and a display capable of running an RDP viewer. When USB devices are plugged into the client, the remote Oracle VM VirtualBox server can access them.

For these remote USB devices, the same filter rules apply as for other USB devices. See USB Settings. All you have to do is specify Remote, or Any, when setting up these rules.

Accessing remote USB devices is only possible if the RDP client supports this extension. Some versions of uttsc, a client tailored for the use with Sun Ray thin clients, support accessing remote USB devices. RDP clients for other platforms will be provided in future Oracle VM VirtualBox versions.
