I recently changed the USB cable of my Logitech G402 mouse and replaced its skates, but after doing this the mouse has become very sensitive to the mouse pad surface. At some areas of the mousepad it will respond according to its set dpi but in some areas it will slow down a lot. Also when the mouse is sitting Idle the cursor moves left and right rapidly on its own. The mouse worked fine on this mousepad before the replacements were done. Everything is the same as it was before replacing the cable and skates.
