Tagus released the driver software Release 5.6.1 adding support for Ubuntu 22.04. This version has been validated on a minimal set of Targus Universal Docking Stations (UDS) and should work with any Targus Universal Docking Stations models DOCK1XX, DOCK3XX, and DOCK5XX. See release notes here.
If you have noticed an odd message while using a Targus docking station for external monitors, you are not the only one! Please contact your Targus representative or DocKtor for further support or more information.
