How do I trace USB disconnection / connection sounds?

[Quartz]

Yesterday I was getting a lot of USB disconnection then connection sounds. How do I trace their origin? There's nothing in Notifications and I've not spotted anything in Event Viewer. Windows 10 x64 v2004

Ahh, I had a very similar issue, probably not what you want to hear; I reinstalled (reset) Windows. I updated to 2004 a few days ago, only the gremlins reared their head recently so I could not roll back.

All USB devices kept randomly disconnecting, my hard drive enclosures, mouse and keyboard - Drove me nuts. I could not find a fix so did a reset. All is well now.
