Freeze + crash "too many USB devices connected"
[This is a repost of a question I also posted on the PS4Pro board but since it hasn't gotten even a single comment after 10 months I am now trying my luck on this more active board]
So I have a first gen PS4 Pro and it started crashing every 20min to 8h or so (I didn't have it crash in sleep mode yet if that info is useful)
I have headphones connected through the TV (HDMI) and there is usually a static sound for a fraction of a second and the controller disconnects (with the last input being held until it crashes). 2-10 seconds later the console crashes.
It also happened when connecting the headphones over the controller.
Sometimes it also just freezes and plays a loud static sound until it crashes (again 2-10s).
Sometimes when it crashes it shows a message that too many USB devices are connected (when not a single device is actually connected)
All the usual steps didn't work. (Rebuild database, reinstalling the system software, replacing HDD, cleaning out any dust from the fan etc. All the ones mentioned here I already tried so no use recommending them to me again)
Before I try anything expensive or risky (replacing the PSU, reballing the APU etc.) it would be nice to know what might actually be the problem. Any advice whatsoever is welcome!
Haven't used it in a few months now. Just used it again and it hasn't changed. Though now I'm relatively sure it's not actually related to the software used but instead just completely random.
Because of the too many USB devices connected error I am pretty sure the console is short-circuiting somewhere. I still haven't found any fixes about this online over half a year later and also haven't put it into any repairshop because I don't want to spend money when they can't guarantee the can't fix it (and will take the money even if the can't fix it which is what most German repair shops do…). With there being basically no information about this online I also don't think many repair shops would be able to fix this so going to one would have a high risk connected to it.
It would be nice if anyone could say if they have any idea on what's going on here, or what I can do to find out what's going on with it.
If anyone on here knows any good repairshops in Germany that won't charge if they can't fix it that would be nice too.
(Not something like gamestop where they only refund you in gift cards…)
