Attach a serial port and find me and we can check the status of a few of
the EC ram variables.
Sort of sounds like the EC thinks there is an ALPS controller connected
rather than the EnE. However that's check every time the host power ups
so I wold have expected a host power cycle to fix it rather than having
to do an EC reset.
To really debug this though I need it to happen on a machine with an EC
serial port loaded.
