We have a damaged touch screen that doesn't work anymore (on panel MP 377 12 Touch). We also have a replacement touch , however it has 4-pin connector and works through USB controller (USB ETP-4500UG Touchscreen Controller). The drivers for that controller are available, however they are supposed to be installed during building of the OS (WinCE 5.0). We have managed to install this drivers to the panel (copying dll's to \Windows directory and manipulating windows registry). We achieved that touch screen communicates with its own configuration program on the panel (calibration, drawing test are performed correctly). However it works only within this program. So we couldn't move mouse when we are out of the program e.t.c.. So the question is how we set the USB touch as an input device? Which changes shoud we make to the registry?
