I looked around about this and slept on it!
The most plausible thing I read where someone had this problem was a USB mouse, that when moved around in a certain way, experienced some kind of loose connection that when moved in just the right way would disconnect/connect and generate the device disconnect/connect sound.
It seems far fetched, but makes some sense. Nothing gets put in the Event Log either for these things that might help track it down either!
Do you have a USB mouse, keyboard? Do you have some spares you could try temporarily? Can you unplug any USB devices and plug them in a couple times (on both ends of a printer) to freshen up the physical connections? What are your USB devices?
If you go to Control Panel, Sounds, you can play the connect and disconnect sounds and hear they are noticeably different. When you hear your sounds, do you first hear the disconnect sound and then the connect right after that? Do the sounds always come in pairs off disconnect/connect?
Are you moving your mouse/keyboard around when it happens?
I know it's a long shot.
