Yes OK -- I will check. But as far as I know the 0xfe-answer from the
touchscreen means: "Please resend the last command". And 0xfc means:
"Error I didn't get that".

I also checked my original standalone-driver: Because of this behaviour
I always retried the last command 3 times if the responce from the
device was 0xfe or 0xfc.
