Where do these links point to? Care to run "tree"?

There are also kernel "ts" input devices, "touch" sounds like a class
name for them. Is that in any way related to this class of kernel

Why do we rename a detected "USB mouse class" to "stylus"?

What's the difference between the two input devices this tablet creates?
