The Tether Tools TetherPro 32 Feet USB 2.0 Extension Cable is an active extension device. Active extension cables allow for longer tethering distances without worrying about signal errors or corrupt data transfers. With an active USB device, signals and data transfers going in and out of the extension cable are buffered to ensure consistent signal quality and caliber, meeting USB's highest electrical and timing spec.
Active USB extensions and 1 passive 15' (4.6m) USB can be daisy chained together for a total of 80 feet (24m) before any drop-off in signal or quality is detected. Plug the male side into your computer and then plug your device's USB cable into the female end of this extension cable so that the repeater is closest to your device, not the computer.
