You didn't say if the controller was reset by the kernel prior to
scanning for devices.  I've had problems with my system doing that if
it doesn't reset the bus after downloading sequencer code.  It's looking
at a flag from the controller to see if the bus has been reset, but
sometimes it still needs to be reset anyway. (flag wrong? bug?)
