touchscreen on Toughbook cf-19 doesn't work

Greetings, all--

I have a Toughbook CF-19 (MK4, CF-19RDT5A1M) with the dual touch screen. I know that the touchscreen works because of the diagnostics tool in the BIOS says so. Also, here is the output of lsusb:

Also, the output of xsetwacom list dev:

Does anyone have any idea on how to get this touchscreen running?
Thanks in advance.
