Found it by measuring resistance and noticed erratic ohms from 1 ohm up passed 100 ohms, all over the place. Located it by gently flexing the cable and feeling for a weak bend area. Then upon pushing cable together problem gone, but pulling apart right there?! we're talking major mouse/keyboard failure and reboot. Whereupon the mouse would start working again. Fixed for a year longer by extricating the section, shortened the cable there, soldered the cable. This is only good for emergency and the die hards who NEVER want to throw anything away that still almost works.
