Thank your advice, Yi.

I search and reference others articles.
Changing the input device mode to 0666, and now touch is work.
But the point coordinate isn't right, it always appears on left-upper
location.
And this method (change the mode to 0666) is also brute force method.
Anyone can directly access the input device if they want.
So, I have some work needed to do.

Thank you.
