I think it has more to do with qjackctl not polling for the MIDI port
correctly.  Jack doesn't do anything with MIDI, it's just a convenience
that qjackctl has a way of patching Jack client MIDI ports to the devices.

That said, I haven't checked to see whether lsusb lists the BCF before I
start qjackctl when it misses the device.  It may be that something is not
polling the USB in a timely fashion, and that it needs the power cycle to
see it.  While an annoyance, at least it isn't a showstopper.
