Same problem, at first the mouse stopped getting detected. Tried different usb cables no luck. Now I noticed that if I connect the mouse with my PC and let it stay connected ( just connected not working obviously) the mouse gets overheated. I checked it and some of the ICs get extremely hot.
Seems like the ICs have short circuited ?
Any idea, chance to see if this can be resolved ? The mouse is laying dead for months now.
