Teensy as GeneralTouch.com SAW Touch Screen Controller

[paulhewson]

Hello.
I use Teensy with Keyboard + Mouse + Touchscreen Emulator without any problem on Windows OS.

But on Linux based system (Ubuntu), I take out orginal touchscreen controller. And system gives error "No touch controller". But when I plug Teensy 3,2,, There is no error any more.

But the problem is; I say run this code on Teensy, nothing happens on target computer.

TouchscreenUSB.press(0, xvalue, yvalue);
delay(25);
TouchscreenUSB.release(0);


Since I want target computer to recognise teensy as original touch controller, I even changed VendorID Product ID and so on.

Here I add the result of "lsinput" of the original touch controller and Teensy's.. What am I supposed to do? Any help? Thank you.

Hello. Topic is still open. Really I am willing to pay for those who can help me about it. You can write me PM.
