Redirection for USB devices can be allowed or denied during an RDP session using rules and sub-rules for specific devices or device classes. The use of rules is described in detail under USB Access Control.

Important Notes

  • For the Fabulatech USB Redirection, a server-side component is required. We recommend the USB for Remote Desktop IGEL Edition; see http://www.usb-over-network.com/partners/igel/. For details on the configuration, see https://www.usb-over-network.com/partners/igel/usb-for-remote-desktop-docs.html. Please note that licenses must be purchased from Fabulatech to enable this functionality.
  • Enable either native USB redirection or Fabulatech USB Redirection – not both together.
  • Disable USB redirection if you use DriveLock.
  • Ensure that no other hotplug storage device (USB memory stick) is connected before you enable Fabulatech USB redirection. Otherwise, the hotplug storage device is insecurely removed.
  • Generally, Fabulatech USB Redirection might not be the ideal solution for each use case. For details, refer to the general device redirection recommendations of your terminal server or VDI vendor.
