While I wait for the Compute Stick to arrive, I have OpenSTF deployed on my old ThinkPad T430. Plugging the MultiDock into the ThinkPad, it was recognised as three four-port USB hubs (two of them are connected to ports on the third, providing a total of 10 usable ports for devices - 4 on each of two hubs, plus two on the third hub). This seemed like a good start, but of the four devices which currently make up my OpenSTF device lab:

• One works - hooray!
• One is detected, but ADB lists it as "no permissions" so OpenSTF can't use it
• Two aren't detected at all

It doesn't seem to matter which port(s) I use on the MultiDock - each device behaves the same, no matter which port (and thus which internal hub) it's connected to. This means that the MultiDock's original electronics are going to be useless for this project, but that's not a big deal as I've already got an Orico 7-port powered hub on the way which should hopefully work.
