Hello All, I did a:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install raspberrypi-ui-mods

rebooted

I did switched to release channel "Beta"...no updates.

But still the Piface does not come back to life... what else do I need to do?
The last changes are ...

Credit should go where it is due : Robin for creating this driver
Happy that it works for others though !

Hi,
I did a small fix to piface driver that is already integrated https://github.com/domoticz/domoticz/pull/426
Before this fix, my piface2 would not work at all or very randomly (random led output triggered, input count increasing without any input, piface not detected at all)
Hope it will help
