Nope, it's a bog standard laptop mouse - logitech vx nano
What happens, perhaps to a varying degree, in Xvesa, Xfbdev and Xorg (with mouse driver) is that when typing the mouse pointer moves on its own and suddenly acts as though it was clicked and you find yourself entering text somewhere else in the document, web page, tc forum reply, etc.
This happens with and without the mouse on a pad +/- 15cm from the keyboard.
This doesn't happen with Xorg and the evdev driver.
