I have seen that the new Pentium II motherboards that are sold in the market have a USB port built in. Can anyone explain in plain language how the new USB (Universal Serial Bus) ports work?...What are the type of cables needed to connect any device to that kind of serial port?...What kind of device I can connect to that port and what are the features that the device a must have built in to be compatible and work with the system?...Thanks for your help...
