Lol, Odee... It's the texture of the insulator, I'm convinced of it. USB cables are really rubbery and soft (al dente) and distinctly nutty, where other cables are a harder plastic and bitter with a lingering aftertaste.
So far I've lost 3 Plantronics headsets, 1 CH fighterstick, and 1 CH Pedals. I've started spraying all exposed cables with Lysol, hoping that will cure him of the habit... maybe I'll try some tabasco.
