So wait, what's going on here?  I thought the devices attached to school
servers were just run-of-the-mill USB 8388 devices like the 8388
daughterboard of the XO, but different connector, right?

What is the post-boot firmware flash functionality supposed to apply to,
the host-less active antenna? (which is what I heretofore had
understood).
