Argh, I'm an idiot -- had the flashing cable plugged into the micro-USB
while the keyboard was *also* plugged into the USB-A sockets (which I
knew doesn't work and apparently missed when originally debugging this).
Closing as invalid.

@waveform was able to confirm the issue. The line
`dtoverlay=dwc2,dr_mode=host` is present in config.txt. We suspect
this to be a dtb/kernel issue. This is happening on both armhf and
arm64.
