It is actually a "static problem" which was causing the problem. It is documented on microsoft's website. A smalll static spark occurs and can knowck out some USB devices. There is no Fix for Win98 but there is a fix for Win 98 SE. I went to using ethernet for my cable modem connection and now the webcam works again plugged straight into the USB.
