Hi, I have: 1. A Microsoft Surface Pro 3 2. A HooToo 10 Port USB 3.0 Hub 3. A Dell P2714T touch monitor 4. Mini port w/VGA connector to computer With 3 there is a separate USB cord that goes from 3 to 2 for touch capability. 2 goes to 1 using USB port. 4 goes to 1. For some reason this does not work. The monitor works, the touch part does not work. I would appreciate any assistance.
