Please note that the OWC Thunderbolt 3 Dock has two Fresco Logic USB 3.1 Gen 1 host controller chipsets, which control most of the port connections on the dock. Please see the part numbers and graphics below to get an understanding of which USB, media, and audio ports are shared by the same controller (and therefore share the same bandwidth), for each generation of the Thunderbolt 3 Dock.
