as I see in this video, LED indicator is breathing, and all controls are lost.
and after a rebooting, all will be restored.
there is only 1 reason which will cause that. --- PS4 controller's authentication failed.
To work on PS4, PS4 controller must keep good and stable communicating with PS4.
next time when you face this, enable "I/O monitor" in "Settings" of our APP,
and return to "HOME" UI, press your buttons on keyboard or mouse.
you can see buttons are being sent to PS4.
so S1 is working normally.
But PS4 does not respond to these signals.
there are some unstable connections here that prevent PS4 from talking to PS4 controller.
the talking between them is related to the following items:
1. PS4 controller
2. USB cable between PS4 controller and ReaSnow S1
3. USB cable between ReaSnow S1 and PS4 console
4. USB receptacles of ReaSnow S1 and PS4
our suggestions are:
1. check USB receptacles of ReaSnow S1 and PS4
2. try some better and shorter USB cables
3. occasionally, some incompatible keyboard and mouse will also bring this trouble
4. try restoring ReaSnow S1 to factory defaults
1 and 2 -> 80% Possibility
3 and 4 -> 20% Possibility
Maybe this is not a reply you hoped,
but that is the true story.
Any more feedback, please keep us informed!
