I had a high-current device on the same bus. Interestingly, a separate mistake was drawing the 3.3V bus to 5V, but when the high-current device was on the line, it was pulling too much current and bringing the bus back down closer to 3.3V. When I used the battery, which delivered more current, this didn't happen, and so the OpenLog would reset. Nasty problem. Fixed with a separate bus for that current-hungry component.
