The Host Port on the TBT4-UD5 is the USB-C port next to the power button on the front, indicated by a laptop symbol and the “96W” labeling. 

What Happens If I Connect to Other USB-C Ports?

Other USB-C ports on the dock will not work as a host port, and attempting to use these ports as a host port will result in little to no functionality.
