I don't know why ucom0 only works in one direction, but I can
explain the `strange...' message.  After the hub driver turns on power
on a port it then checks the status bits for the port to check that it
is powered, if it isn't you get the message.  But since the umct driver
seems to attach fine anyway I would worry about that message.
