Trackpad and keyboard continuously seen as being disconnected and reconnected by USB daemon. Internet was unanimous that issue was USB upper case cable.

Replaced the part (and replaced a few stripped screws too)... but issue persists. The problem : faulty upper ase cover.

When your mac starts going haywire this bad, don't invest 250$ to fix it. Buy a new computer.
