Works for me on MacBook Pro (even USB 2.0 outputs) very unreliable. Often nothing is recognized, so I have to plug in the new distributor. Even with only one connected device the distributor does not work reliably, so copying to a USB flash drive takes significantly longer than with no distribution in between.
For processing, I can only say that the plugs are relatively stiff insert in this port and that the connecting cable is so stiff that the "connection box" a little in the air depends, if you later / inserts the distribution deeper than one the Box stores.
