Ubuntu 20.04 sometimes stops processing input from Peripherals

[iron-squid]

Hello, I've been using Ubuntu 20.04 for approximately 2 years now and I've started having issues with this about 3 months ago.

During login, everything always works normally and I can use my mouse/keyboard properly.
However, sometimes immediately after login, or quite a few hours/minutes afterwards, all peripherals (Webcam, Mouse, Keyboard, USB, etc) stop working.

I haven't done any modifications to the core of Ubuntu, and I don't know what could be causing this.

Peripherals generally use the 5 volt line, so I would say your most likely cause is a failing or underpowered power supply. Are you using a USB hub? DON'T! Powered or unpowered, these things cause way more problems than most people know.
