If the problem is not from your computer USB ports, then it is for sure the mouse itself.
When it disconnects, try to bend the wire and see if it reconnects, if it does, it is from the wire.
If it doesnt, dissemble the mouse, there is a small round sticker on top of the screw. See if there is any loose components.
If you can get your hands on another PC, get your mouse and try it on it and check if it works well.
If nothing solves the problem,then the last thing is to buy a new one.
