The USB 2.0 Repair Kit includes two USB 2.0 Repair Modules and a Male-to-Male USB 2.0 Cable. The Kit can be used to extend a USB 2.0 Cable, perhaps for better reception for a wireless mouse receiver or if a keyboard cable is too short. Just connect the data and power lines with screw down terminals and you’ll be good to go. You can use this pinout to give you a start, but you should verify which lines are which as there is no industry standard for which colors go to which pins. We recommend using Cat5e/6 for your extension.
