I have a quick question about a control logix cable. Just about any laptop that you buy now has no serial port on it, only usb. I just bought a new laptop with windows xp running logix 5000 and heard that the new 1747-CP3 cable for usb to the plc proccessor has troubles. Just wondering if anyone has had this trouble. The cable is cheap. I am assuming anyhow that this is the correct one anyhow.
