HDMI5 test pads

[VectorX]

On the schematic, they show 5v, D-, D+, GND.  Does anyone know if the data lines are connected to the touch functionality?  They only mention "custom connection via USB protocol" but don't say exactly what it does.

I'm wondering the same. 

The product page only adds the info: "4 pin XH2.54 Break Out Port", which is not very helpful.

From what I am getting on the interwebs, D+ and D- are data pins for USB 2.0 protocol.
