Thanks for the pointer...I do see the board power up though ("Ready to
receive application") so that should mean that power is OK? I don't
have external power, just relying on USB power (which I can turn on
and off for this port).
I basically see this at present:
$ ub-int edison
Building U-Boot in current dir for edison
Bootstrapping U-Boot from dir /tmp/b/edison
USB resource not available; retrying reset with longer delays

I suppose something could have happened to the relays or cables...
