Touch screen not working

I am just setting up my onefinity with the 10" monitor. I originally made the mistake of plugging into the controller. The touch screen was working then but the screen wasn’t full size and the touch wasn’t working properly. I fixed the full screen problem by reading the directions again and plugged the monitor into an outlet with the supplied hardware. But know the touch part isn’t working at all. Anybody know what the problem is?

We had the same issue for over 1 year. Assumed we did not have a touch screen monitor.
Reading through many forum monitor posts, there were suggestions saying to reverse the 2 USB cords.
We received only 1 USB cord with our Onefinity. A trip to Dollar Tree and $1.34 later- We now have a working touch screen. One for power. One for touch screen data.
Still use a wireless mouse most of the time due to habit.

discovered that I didn’t read all the instructions. I needed to the second usb to the controller. Everything works now
