Installation of PiFace Digital I/O Card

[Acoma78]

Dear people,

I am trying to get my I/O card running under XBian.
However, the guide for raspbian does not work:
http://www.piface.org.uk/guides/Install_PiFace_Software/
Also the guide which I have used successfully for openelec 4 does not work:
http://piface.github.io/pifacedigitalio/pifacedigital.html#outputs
(It also doesn't work for openelec 5 which was the reason for me to try out XBian)

Does anybody have experience with the PiFace Digital I/O Card on the pi2?

Kind regards Acoma78
