No touch screen functionality in instalation environment

I’m trying to install openSUSE 13.2 on my Wacom companion 2 with a live usb, but the touch screen doesn’t work, so I have no way of starting the installation. Surpriseingly I’ve been looking around a lot with google and can’t find anything on the lack of touchscreen support in the installation environment, but lots on how people have been running openSUSE on a tablet PC. Is there something really obvious I’m missing?

I never figured out a way to get the touch screen to work, but I did find an old usb keyboard which allowed me to get through the install.
