Very long shot: Does it still work under 13.10 if everything is
powered off and then booted directly to 13.10?  This is based on
a wild guess that there might be firmware that gets downloaded to
the device that enables 13.10 to see it.  (I have a USB-attached
TV tuner that enumerates as one USB device, installs firmware,
disconnects as a USB device, then re-enumerates as a different
USB device once it has its firmware.)

Another long shot: Might it be flaky physical connectors?
