I've blown the USB bus on my old Mac Mini by plugging in a crappy USB hub. IIRC (the machine is no longer with me), some of the ports no longer worked but at least one did which was enough for me to plug a "real" hub in to. Still a PITA.

Edit: that was a 12V powered hub, not "a cable", so maybe that's why.

I once accidentally used a charger rated for much more than the hub I was plugging it into and it fried half the things plugged into it.
