USB 2.0 ports broken after using USBOblivion

I had an issue with my keyboard and so I downloaded and installed the latest Logitech drivers, for some reason (likely just a glitch) my keyboard went from problematic to now being just an "Unknown Device". After many attempts to fix the issue including a clean install of the new and old drivers, and reinstalling AMD drivers for the USB hub I turned to Uncle Google and found 'USBOblivion', which supposedly fixes all sorts of USB problems. Supposedly.


Well it didn't for me. It was a simple to use program, just tick a box and click 'go' and it tidies up old 'ghost' entries in the registry, but for me it broke all of my 2.0 ports. My 3.1 and 3.0 ports still work, but I have seven 2.0 ports which now show a yellow exclamation mark next to anything I plug into them with a "Code 10 - This device cannot start" error. All drivers install fine, and I've even plugged in ancient devices from the cupboard to see if the problem is only related to things that were present when I ran USBOblivion but they do exactly the same which leads me to think it's a hub problem. Except I've uninstalled/reinstalled all of the hubs and all are working fine, no errors.


I can't use system restore as the only 3 restore points it has after all post-USBOblivion and would restore me to the same state.


I have a .reg file from USBOblivion but it fails to import as "some keys are open by the system" even with Admin rights, also this file is over 500KB so it has me wondering just what the hades that program ripped out of the registry that requires a half MB backup.


What I have been searching for for days with no luck is just some way to reinitialise or reset USB to a clean slate. DISM and SFC scans say all file integrity is pristine and Windows 10's built in hardware troubleshooter just attempts to reinstall the 'code 10' devices in the same way that I tried manually by uninstalling and re-scanning for them. No change, they just reinstall with code 10.


Any suggestions?


Windows 10 Pro x64 v1803 b17134.191 fully updated
MSI X370 Titanium motherboard
ASMedia ASM2142 Chipset
2x 3.x ports (working)
AMD CPU
4x 3.x ports (working)
AMD X370 Chipset
5x 3.x ports (working)
7x 2.0 ports (broken)


PS. I know some folks will say "Forget about it, you have enough USB 3 ports!" but the thing is that only 4 of the rear ports are 3.0 and compatible with my devices, the rest are 3.1 and have different sockets, and all of the other 3.x ports are on the motherboard.

There is no guarantee this will work, but If you go into device manager, and delete ( right click uninstall) the entries with a yellow !, on a reboot windows should reinstall them with the correct drivers. It's likely the host controller that's borked.

That seems to be a more-advanced motherboard than what I use with my AMD CPUs so would wonder if there's software for it that allows changing the BIOS from within the Operating System. Traditionally the BIOS supports USB 2 before any OS loads but USB 3.x needs software drivers which load with the OS. In such a situation as this I boot to a bootable Linux LiveDVD to check support for the hardware, see if things that should work actually are. Nice thing about such a disc is it is a full program, doesn't have to be actually installed. I've even got it running on a USB Thumb drive in a computer with a bad HDD that can't physically be replaced without further damage to the case/board.

If all else fails, an upgrade repair install should set things to rights. Here's a link to the TenForums Tutorial on that subject: Repair Install Windows 10 with an In-place Upgrade.

@krashd: I hear you loud and clear, and I feel your pain on the clean install front. A repair install is much less effort, though, and doesn't involve re-installing & re-configuring your apps and applications as is the case with a clean install. Good luck with your repair efforts.
