I was given a PiFace as a present. Installation went fine and I got the Manchester train times info up and running. Then the problems began.
A few minutes after starting the Pi with the PiFace attached my mouse will stop working. Another strange effect is that the caps lock light on my keyboard does not work. If I unplg the PiFace then everything is fine. Mouse and Keyboard are plugged straight into the Model B as usual.
Anyone else seen this?
