B450-F Gaming - No USB ports work. They give power, but doesn`t recognize anything I connect

Level 7

Please help!
As the title says, none of the UBS ports on my motherboard work all of a sudden. They give power (a USB connected mouse lights red, but nothing else), but don`t recognize any units I connect.

Luckily I found an old PS2 keyboard so I could navigate the UEFI and Windows, and for the first time I can say I am fairly happy I`m an eighties kid; Navigating windows without a mouse goes surprisingly well, probably since my childhood was spent on on TIKI100s and 286s 😃.

What can be the reason to all USB ports (both front and back) failing, and how can I fix it? It`s terribly annoying, and with me having ADD, I can`t let it go of it either. I have now spent the past 48 hours trying every single possible solution, but have to acknowledge that I am coming out short. This is what I have done:

  • Cleared CMOS by removing the CMOS battery, disconnecting the PSU and "short circuiting" the CMOS pins.
  • Tried disabling and enabling the USB ports with "DisableUSB Free".
  • Removed everything but 1 RAM stick and the CPU and PSU to see if there were any compatibility issues.
  • Googled and Binged my butt off for hours, reading 500 different forum posts about (almost) the same issue.
  • Asked Chat GPT4.
  • Reinstalled these: Oyvindli1_0-1685910525104.png
  • Tried installing this old Windows update: Oyvindli1_2-1685910575524.png "March 5, 2018—KB4090913 (OS Build 16299.251) - Microsoft Support"
  • Uninstalled all USB root drivers in device manager, and restartet the PC in question.
  • Tried installing Armoury crate to see if it would update my MB in some magical way, but I can`t navigate to the "front" to accept and install it properly. no matter what I do, I keep navigating around in "the back". Anyone know a smart way to move the navigation "up a layer" so I can accept and install? And will it even have a chance of working?

Nothing have worked so far so I really hope someone here knows the solution. I found this program called USB tree which gives a lot of information, but I don`t know what all the info means. Maybe some of you can read something sensible from it?
