Are the controller and miner firmware both the same version? Both have to be the same or Avalons will not run.
Also missing from the log is any information about the AUC3 dongle. Right after the board info (MW0, MW1, MW2, MW3) should be this:

[STATUS] =>
giving communications status of the AUC3
edit: Should also add to be sure that you are using a USB
data cable between the RasPi & AUC3 vs a charging cable. Charging cables often only have 2 wires in them and will not support data xfrs.
