When booting an unmodified version the usb ports do not work. After an inspection with journalctl I find the error message "No bus number available for hot-added bridge" and a google search led me to this workaround: Add pci=realloc,assign-busses,hpbussize=0x33. This line as a boot parameter makes the dock work as intended. I believe this should be fixed so that people using the live image can see that their hardware works as intended before installing.
