I have a feeling the reason why this can't be is calibration
I was curious if there are any touchscreens that get recognized as a Human USB Interface Device without the need to install 3rd party drivers. Basically that would theoretically work on any OS/platform.
Does such a beast exist?
Well, I guess you could have a touchscreen that works to control the cursor as a USB HID device but is calibrated by some other USB interface. AFAIK, though, nobody is making such a thing.
I guess you didn't like my answer in your other thread about the Lilliput needing drivers to work with the Xbox.

you won't find one like that
