Maybe faulty USB extension cord, bad USB hub, try swapping ports on PS4, etc etc.
I think you are referring to the other mod. I was talking about this one: https://www.thingiverse.com/thing:3427473It's not only about the size but also rating as well. The original one is M10 rated at 1-3 N as I recall. I did change it with 2 (I have the th8rs with the second hole tapped as well) M10 rated 6-10N and its night and day.
No, I was generally explaining about spring plungers, that size is not the only thing that matters, but rating as well. Whether you use then in the aforementioned mod, or in my mod, you can choose between different strenghts of plungers of the same size.
