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 or Fabulatech USB Redirection – not both together. Disable USB redirection if you use DriveLock.
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 securely removed when the session starts, and this could lead to data loss. With IGEL Linux Version 10.02.x the Hotplug storage device is already insecurely removed when the Fabulatech USB Redirection is enabled.

Default rule: This rule will apply if no special rule was configured for a class or a device.

  • Deny
  • Allow

    Tip

    To secure your endpoint, it is generally recommended to set Default rule to Deny and to configure Allow rules only for the required USB devices and USB device classes.
