Random USB Mouse disconnect sounds

My beloved Dell desktop kept making random Device Disconnect system sounds - but not Device Connect sounds.    It seemed to happen mostly when I move my mouse over windows which were rendering heavy graphics, ie. a webpage.

I got annoyed with the system sound happening several times per hour.  Fortunately a program called USBDeview helped prove it was my mouse disconnecting as the "Created Date" kept updating when I heard the sound even though my mouse moved and didn't miss a beat.  So time for a new mouse.

I don't know why there was no Connect sound or how the "Last Plug/Unplug Date" didn't also update since my mouse kept working.   Regardless, USBDeview is a good tool for your toolbox.
