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 .
Anyway:
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:

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?














- AMD Rysen 5 2600X.
- ROG STRIX B450-F Gaming.
- Corsair VX550W.
- Cooler Master Hyper 212 LED Turbo.
- 4 x 8 GB Corsair Vengeance LPX DDR4, 3000MHz.
- MSI GeForce GTX 1070 8GB DDR5.
- 2 x Intel SSD 256GB M.2 PCIe NVMe 2280.
Please help. I need the USBs to work :-(

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: https://prnt.sc/nS1y3BiWgKmD
- Tried installing this old Windows update: "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?
