That tells me that if you power ON again about 1-2 seconds after powering OFF, the 5V VCC rail is still at about 1.7V. Question is does the subsequent Power ON try to drive VCC above 5V ?
No, it did not appear to do so. ?If you look at my original scope traces you can see that VCC starts right around 1V because I had been turning the QMX on and off as I adjusted the scope trying to get a good view of things and it had not completely bled down.
