Configure HP TouchSmart touchscreen

I have an HP TouchSmart IQ507 with SuSE Linux 11.0.

I’m trying to use sax2 to configure the touchscreen.
It’s asking me two questions:

  1. Touchscreen Vendor (ELO, Fujitsu, Microtouch, or Mutouch)
  2. Device name (USB, Com-1 (/dev/ttyS0), Com-2 (/dev/ttyS1))

I’ve tried all these combinations, but none work.

Does anyone know how to get SuSE to recognize the touchscreen?
