Okay. Then how about this: Unplug both the power connector and the slave connector. After the N7 goes into deep sleep, plug the power connector back in but leave the slave unplugged. Then a few seconds later, plug in the slave.
This always fails (-71 / SET_ADDRESS). The issues can then only be solved, by unplugging the "OTG" adapter. In other words, by switching to peripheral mode (and back).
Also try doing the same thing, but don't wait for the N7 to go into deep sleep. If this works but the other test doesn't, then clearly the slave is working correctly and the problem lies in the host controller.
This works well most of the time. Some issues in a few cases, not sure why. (It is possible to debug over WiFi. But doing so would prevent LP0.)
