Fabulatech USB Redirection for Citrix in IGEL OS
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.
