[PATCH 1/6] USB: don't unsuspend for a new connection

This patch (as889) prevents the hub driver from trying to resume a
port when there is a new connection.  For one thing, the resume is not
needed -- the upcoming port reset will clear the suspend feature
automatically.  For another, on some systems the resume fails and
causes problems.
