We are working with MCF51JM128

Most of the time we are in STOP3 mode, waking once a second or on external interrupt.

As soon as we connect the device to a USB cable ( connected to a PC ot to a charger) we enconter Illegal address detect reset.

We have cheked all our vectors / pointers etc, but we do not see any of them that are not initilized properly.

Does anyone have an Idea why?
