The supplied cable is a 1m (39") USB to RJ-45 style. The cable I received uses a genuine Prolific chipset and requires no special drivers. It will load the current required driver directly from the internet.   Note: I have been told that some vendors are supplying cables that require a backdated Prolific driver. If this is the case, Prolific Driver 3.2.0.0 can be found at DRIVER
