I have a raspberry and tested the screentouch program with two different touchscreens, but both failed with the following error:

$ bin/linux-armv6l-dbg/screentouch /dev/input/event0
Device /dev/input/event0, eGalax Inc. USB TouchController, is not a touch screen.
No touchscreen found.

and

$ bin/linux-armv6l-dbg/screentouch /dev/input/event1
Device /dev/input/event1, ADS7846 Touchscreen, is not a touch screen.
No touchscreen found.

the error seems to occur in main.cpp line 107 on evin->numSlots() < 0

I am using current debian 11 32bit with libevdev 1.11

evtest delivers:
