I bought this touchscreen for my Pi. Screen works perfectly but the touch controller does have some problems. It is recognized by my Pi as Touch, at least it says it in the connected devices scection. Now here comes the problem when I use the touch, furthermore when i click for the first time it recognizes my action and it works but thats it, after 1 action the Touch doesnt work anymore even though the LED on my Touch-controller still lights up when I touch the screen.

So all in all, my problem is that I can only touch once, afterwards it doesnt work anymore. Anyone has a solution for that or maybe any universal dirvers?

  • Power supply! You need more juice!

  • I have 2000 mA power Supply, that should be enough, right?

  • Should be.. maybe its not. What power supply is, and how do you have everything connected. Can you post a pic of the connection and how everything is powered up.

  • It should be adequate, though you could try with a shorter USB cable since long or lower quality USB cables sap juice quite quickly. You can also try measuring the power output of course, given you have the tools for it.
