Yes, hpen(4) supports them.

It is required to apply some quirks though as TouchScreen usage page is handled with hmt(4) driver by default.
Try attached patch and don't forget to enable usbhid(4) to use it with addition of following lines to /boot/loader.conf:

hw.usb.usbhid.enable=1
usbhid_load="YES"

P.S. I am not subscribed to usb@, so keep me in CC.
