Redirection for USB devices can be allowed or denied during a Citrix session on the basis of rules. Sub-rules for specific devices or device classes are also possible. The use of rules is described under USB Access Control.

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/

  • Fabulatech USB Redirection

    Fabulatech USB redirection is enabled for all Citrix sessions.

    Enable either native USB redirection or Fabulatech USB redirection, but not both together.


    Disable USB redirection if you use DriveLock. Further information can be found in the Using DriveLock with IGEL Devices FAQ.


    Ensure that no other Hotplug storage device (USB stick) is connected if a session is started with Fabulatech USB redirection. Otherwise the Hotplug storage device will not be safely removed when the session starts, and this could lead to data loss. Please be aware that in IGEL Linux 10.02.x or higher, any USB storage device that may be connected to the thin client is automatically unsafely removed upon activation of Fabulatech USB redirection.

    Fabulatech USB redirection is disabled for all Citrix sessions. (Standard)
