Question Completely losing USB?

[beatle]

A couple of days ago, I rebooted my desktop to clear out an issue with my keyboard (G915) not syncing properly with Logitech G Hub, and when I got back into Windows, I had no input peripherals (keyboard or mouse) at all. I reset and there was no change. I tried safe mode and even that had no peripherals. I still had them in BIOS, but not in Windows. I tried a spare wired keyboard and mouse (actually a couple of them) and none would show up. With no other options, I did a restore (Acronis) from a week ago and brought them back, though after I rebooted again, I lost my peripherals once more.

Any ideas here? I tend to blame Logitech's awful software as it always seems to be terrible, but I don't really have any other options with this setup. It may also be something else, but without any peripherals to navigate the OS, I have no way to troubleshoot.

Have you tried connecting a smartphone to the computer to see if it detects that?

Have any ps2 ports? If you have a ps2 port You could pick up some ps2 adapters or a ps2 mouse and try that with onscreen keyboard if you only have 1 port.

Otherwise pick up an m2 bluetooth adapter (usually paired w/ wifi) and try a bluetooth mouse/keyboard

I did not try a smartphone, though I suppose I could.

The machine did another restore last night and I booted it up to find it was okay, though wants to install a USB receiver. I went to uninstall G Hub and the process stopped running about 2/3 of the way through, so I rebooted. The compute again was stuck on Restarting, so I hit reset. When it went back into Windows, I had lost USB again.

This makes me think there is something wrong with my motherboard as my restore was from 3/10 (my 3/17 backup was corrupted, keep multiple versions!) and I did not start having these USB issues until 3/17, so it seems unrelated to any software change.

This board doesn't have PS/2, else I think I'd be out of the woods. I do have a bluetooth adapter, but it is USB. I didn't know they made M2 bluetooth, but that's worth investigating as a safety net.

Maybe I missed it, but what is the board in question, what is your PSU, and how old are they?

 

[beatle]

It's been a while since I've had my rig's specs in my signature...

Board is a Gigabyte Z390 Aorus Pro, about 2 years old

PSU is a Corsair CX750M, about 7 years old.

Hmm if it's not software, I'd check to see if your smartphone can charge on the computer's usb ports. Could be the 5v on the psu is having trouble outputting at low system loads. I don't think all the deep idle states are active during post/bios. If it can't you might want to try another psu.
Is the computer on a protected outlet/surge protector/ups?

How old is the OS drive?
Some other things to try might be to check drive SMART data, run a virus scan, or run memtest, since there seems to be some weird stuff going on with corrupted restore points.

I didn't have an issue with USB during the restore, and that goes into WinRE. I initially had a bunch of problems with the restore and decided to reload Windows. No problems there either.

I might still load Windows fresh and see if I can get it to fail.

My mschine is now in a strange grey area. After my last restore, I booted the machine up, but was slow in moving over the USB dongles from my work laptop to my personal desktop. I didn't get the mouse dongle plugged in until after POST, but before getting to the desktop. Now I have no mouse, but my keyboard functions, so I can limp around through the GUI to check things out, Some interesting things:

1. Windows has a "USB Receiver in device manager under Other Hardware that is not working, but I cannot remove/uninstall it. When I scan for hardware changes, it never finishes.

2. I cannot uninstall Logitech G Hub. It now says that it uninstalls successfully, but it never actually does. It also cannot start; it simply sits at the animated splash screen forever.

3. I can charge my phone okay, and I have a spare backlit keyvboard that lights up when plugging into USB. All USB ports are effectively dead from a Windows perspective, however.

looks like something is corrupting your OS files. You should run a memtest and verify your OS drive is working properly by checking SMART.

Probably either file corruption or a windows update that keeps getting applied after your last restore?

Then again, with a 7 year old PSU, I'd pop it open, see if the 5VSB capacitor(s) have failed, and clean dust out while it's open. If there is a jumper or bios setting to toggle USB between 5V and 5VSB, I'd also set that to 5V.

Do you have an idea why your last backup was corrupted? I mean is this potentially CPU or memory instability, or more likely that after the backup was made, it was transferred over a flaky USB port?

I punted on Saturday and decided to just reinstall Windows from scratch and migrate data from my backups. Kind of a hassle, but things are still working as they were before the failure.

If I had to guess, I'd blame Logitech's software for screwing up USB. G Hub is still somewhat flaky with some button functions on my G602 working and then mysteriously not working until I rebind them. It amazes me how poor the software of a first tier hardware company can be.

I keep a close eye on the health of my drives with Stablebit Scanner, and they are all clean. I suppose I couldn't rule out memory as an issue either, but I haven't had a lick of instability otherwise. We'll see how stable things remain after this reload.
