Were the other PSUs also Canaan sorcerers?

Yes, they were all the same unit Canaan ships with the Avalon 741

How are you powering the Pi?

USB cable with a 3.0 amp plug (also tried 0.3 A -- too low, and 1.5 A.) I have ordered an official RPi3 power supply that I'll test

I'm thinking the power issue is the miner not starting. I've never had the AUC itself show up (without the miner), but I only have 5 of these so not a huge amount of testing with it.

This is actually very helpful. I was unsure if the converter would show up alone if it's not connected to a miner. If it doesn't show up until a working miner is connected, then I have a few points of failure to test (not just the connection between the controller and converter.)

The miner does power up with green lights at the back and an amber light on the front -- could this still happen if it was underpowered?
