Hi. I am planning to open a small hardware repair facility at my town. These days I try to learn as much as I can, about the various things that have to do something with hardware. I want to know all about the various types of usb ports. What are their kinds and with how many devices and gadgets are they being used at present? Which of the usb ports gives you the fastest transfer rate when it comes to data transferring? Please get me all this info in your answer. Thanks all.
