Many modern laptops use i2c for hid, but I do not know if your laptop is using that. Anyway you could try it. As far as I know, there is no officiall support. Nevertheless, there is a review for implementing hid over i2c here https://reviews.freebsd.org/D16698. Touchscreen support for i2c over hid can be found in this repository https://github.com/wulf7/iichid.
