To everyone who, quite rightly, called me out on the Apple Ethernet/TB adapter working with this hub (some of you pretty agressively

) - it is official: You are all completely correct
I raise my hand up and will take it like a man. I was completely wrong, no conditions, caveats, or excuses. Put it down to a (very rare IMHO

) moment of stupidity on my part. I'll even leave all the posts above unedited so you can all have a laugh at me.

...and those that don't read whole threads can continue to make new posts about how dumb I was.
I want to post this because I don't want to discredit the people making this hub. As suggested by others there was a miscommunication between myself and them. I wrote them this morning again, explained more clearly what I was asking, and that I had received some backlash on their answer to my question. Again it only took about 5 minutes before they came back with a clear answer that it would not work, as the mDP port is only being fed full DP 1.2 compliant signals, nothing else, so it is indeed a standard, good old fashioned mDP port.
They apologised for the misunderstanding and have even offered to move me up to the next pledge level for free for my troubles.
