When I use my computer, my mouse is unplugging automaticlly and I have to re-plug it to work, what's this?

Are you using any haardware which takes a lot of power? For example a keyboard with a display or something like that. It could be possible that your mouse isn't getting enough power.

Could be a trojan also which has access to the machine.
