Does anyone know why the USB port has two ground / neutral / mass cables on the board side (i. e. on the other side of where you plug your equipment in)? I have an Epox mainboard, BAT sized, and just bought the USB connector thingie for it. What I noticed is this: the USB port has FOUR visible sprockets, the USB-socket-to-mainboard cable has FIVE wires, and the mainboard has FOUR sprockets. When I took it back to the shop, the salesperson told me that the fourth and fifth wire were both DC - ground, so that the fifth wire "wasn't really needed". I find that a bit hard to believe. Can anyone tell me what this fifth wire IS and what it DOES? Please e.mail me as well as replying to the group. MANY thanks in advance.
