The cheapest and easiest way to extend the length of a USB cable is to use a standard USB extension cable, which is available in the market. These cables have a male end and a female end that are easily connected to the desired device and port and work. Of course, to use this type of cable, you must keep in mind the length limit mentioned above (5 meters for USB 2.0 and 3 meters for USB 3.0) so that the total length from the beginning to the end of the connected cables does not exceed that. Active USB extension cable has an electronic chip that reproduces and amplifies the USB signal. Active cables are basically a 1 port USB hub. You can use regular USB cables to connect to the Active cable, as long as they are no longer than 5 meters for USB 2.0 and 3 meters for USB 3.0. Note that, normally, active cables are Bus-Powered; This means that they receive the necessary energy from the same USB port (simultaneously with data transfer). Use high quality active cables or converters with a separate adapter input to ensure you get the full 500mA power of the USB port.
