I know this doesn't necessarily fix the issue, but my computer kept making the USB disconnect sound because of my iCUE software so instead of trying to fix my software I looked up how to turn off the USB Disconnect sound. It has been so peaceful ever since lol.
If you want to just disable USB sounds, either:
right click on the volume icon in tray and select Sounds or:
go to Settings -> Personalization -> Themes -> Sounds -> Sounds
Then in Program Events disable:
Device Connect
Device Disconnect
sounds by selecting {None} for them in the dropdown. You don't have to disable everything as in selecting no sounds for Sound scheme. Then you can also save the new scheme as a separate entry in case you want to switch back to the original.
