Problems with Antminer U1 – why doesn’t it work?

I’ve got other Antminers working, this one just throws these errors in debug mode – is this fixable?

I’m running cgminer 3.9.0 from the fractal branch, though all the versions that support the antminer-u1 seem to have the same results, so I don’t think it’s necessarily the miner software. I’m running with these options to underclock:

--bmsc-options 115200:20  --bmsc-freq 0681 -D
