i wonder how this will work out.  it makes realtimeish impossible.
we measured 100ms intervals where the usb legacy stuff had
grabbed the processor and wouldn't let go.  (fortunately we could
turn that off.)

if things get to the point where these things can't be turned off,
we'll need to find other hardware.
