Unsolved QML & touch screen => evdevtouch: Could not read from input device (No such device)

[MHermann]

Hi,

I have a QML application which uses a touch screen as input Normally everything works fine.
But after restarting the touch screen, I get the following error message:

evdevtouch: Could not read from input device (No such device)

When receiving this message, touch screen events are not longer recognized. The application itself is running, because I see the time is inkrementing in the application.
After restarting the application the touch screen is working fine again. I don't have to restart the whole system.

Does anyone have an idea what could be reason for this error message and how I could resolve it?

Kind regards,
MHermann
