USB Hub on monitor non-functional I have a late 2012 Mac Mini running Sierra. I have it set up with a Dell U2715h monitor via the thunderbolt port on my Mac, with a miniDP -> DP cable, as the only way to get the full QHD resolution support.

The monitor has several USB ports (USB3 I think) which could be really handy - except they don't work.

I can't find any settings for this on the monitor but as I understand things, the DP/thunderbolt cable should be providing USB connectivity. How can I get this to work?
You need to connect the USB separately, using a standard USB A -> B connector.



The USB input port on Dell monitors is usually underneath, near the video ports, example below...
