sentences:  The Rio 500 has a USB port that looks like the standard 5-pin mini-B type, however it is not compatible with modern USB mini-B cables.The USB1.1 spec was released in September 1998 and the 500 didn't go on sale until a year later, however the spec for mini-B cables and receptacles was not established until October 2000.Before then, some digital cameras had adopted the mini-B connector using a pinout with the data lines reversed (relative to spec) and the +5V line disconnected; the Rio 500 also had adopted the pre-out October 2000 pinout.
