Mouse issues often stem from physical damage or interference. Disconnecting could signal a paracord or similar obstruction. This might block power to the motherboard or disrupt USB connections. Voltage loss isn’t typical unless a short occurs. Most reports suggest a short circuit rather than voltage failure. Seek professional help if unsure.
It relies on the cord's condition and how conductors connect. When +5v touches ground, the USB controller might cut off that port because of the unexpected current. If data pins short together, the computer won't process the data properly and may think the device was removed. A broken power ground makes the mouse behave as if it was unplugged for a brief moment. I'd stop using that mouse and get a new one.
