i build a new PC but my all the 4 "usb 3.2gen1" port on the motherboard doesn't work at all. all other ports work fine, like"usb 3.2gen2" and USB on case,they all work fine,except 3.2 gen1.
i tried resetting and updating my bios and the USB is working after that,but when i restated the computer it died again.
on Universal Serial Bus Controller has an unknown device with error code 43, when I reset the bios it disappeared and turned into a universal hub, when I restarted the computer and the unknown device reappeared, the universal hub disappeared and USB ports died again.
I also tried reinstalling the drivers but it didn't work. I not sure if its a defect in my motherboard or what

I have been having the same issue with my new pc with a Asus mb. all usb worked expect the 3.2 gen 1. In device manager it showed up as an unknown device. I tried reinstalling drivers and nothing worked. I found out that i ONLY got that error if i had somthing plugged into the case usb. Once i unplugged the device from the front IO the 4 usb on the back of my motherboard started working.
I have the exact same thing happening on my computer. 4 USB slots on motherboard not working. Computer is ~7 months old, and worked flawlessly, untill a few weeks ago.
Have updated bios, chipset, windows (even reinstalled), and still none of them working. It is also the 3.2 gen1 slots. (i noticed that pattern, and a google search brough me here). When I plug into the port, no reaction. nothing.
I've tried all the recommend things mentioned as well.
My motherboard is the ASUS TUF Z790 WIFI PLUS.
Curious if original poster found an answer.
EDIT: After lots of frustrations I found a recommendation to clear the CMOS. I cleared the CMOS and now the gen1 ports are working again. Going to be interresting to see for how long ^^
Funny I have the same problem and the same motherboard. So I am thinking it have something to do with the motherboard type . But thanks for the tip to clear cmos 😁
Hi , Evan_Cyc
Good day! My name is Vishal . I am an Independent Advisor of Microsoft and a Windows expert . I am glad to be able to provide assistance for you today.
Here are following Steps for troubleshooting:
1- Please do the Window update and restart your computer
2-Please Visit the motherboard manufacturer's website and download the latest chipset drivers for your specific motherboard model. Install these drivers to ensure proper functioning of the USB ports.
3-Open Device Manager and locate the USB controller section.
Right-click on the device showing error code 43 and select "Uninstall device."
Restart your computer and let Windows reinstall the USB drivers automatically.
At the last if all the above steps do not work than please do the fresh window installation
If the problem persists after trying these software-based solutions, it's possible there's a hardware fault with the USB controller on the motherboard. Contact the motherboard manufacturer's support for further assistance, especially if your motherboard is under warranty.
Hope it will help. Please let me know if you need any further assistance .
