* listening to this keyboard, so we go into the timed_out state. In this state we assume
* that hid_listen is most likely not gonna be connected to us any time soon, so it would
* be wasteful to write follow-up characters with a 5ms timeout, it would all add up and
* unncecessarily slow down the firmware. However instead of just dropping the characters,
* we write them with a TIME_IMMEDIATE timeout, which is a zero timeout,
* and this will succeed only if hid_listen gets connected again. When a write with
* TIME_IMMEDIATE timeout succeeds, we know that hid_listen is listening to us again, and
* we can go back to the timed_out = false state, and following writes will be executed
* with a 5ms timeout. The reason we don't just send all characters with the TIME_IMMEDIATE
* timeout is that this could cause bytes to be lost even if hid_listen is running, if there
* is a lot of data being sent over the console.
*
* This logic will work correctly as long as hid_listen is able to receive at least 200
* bytes per second. On a heavily overloaded machine that's so overloaded that it's
* unusable, and constantly swapping, hid_listen might have trouble receiving 200 bytes per
* second, so some bytes might be lost on the console.
