What is supposed to happen is that the controller decides the endpoint
is temporarily inactive when the NAK counter reaches 0.  When all the
endpoints on the async schedule are inactive, the controller pauses the
schedule for a little while (around 10 us).  Then it restarts the whole
procedure, reloading the NAK counters from the RL fields.

You cannot control the duration of this pause; it is built into the controller hardware.

That's unfortunate; I would love to be able to slow it down some more. If anyone can suggest any nasty hacks to achieve that, please share....
