This brings up a question I've had in my mind a while. I have at least one or two usb cables that have what appears to me to be some type of isolator or something on the cable, a farrite bead perhaps? I was considering using this cable and leaving it connected to the machine so I wouldn't have to dig up the Bp's cable which I carry in my bag to work. Would this thing on the cable pose any problems? Sorry for the question, but never got around to asking what that thing could be and just assumed some type of isolator. tnx Scott
