Suck USB extension cable mostly nothing (yes even at 2 meters is nothing more through), make passive repeater like this would expect always more than one. Although they require no separate power supply and additional power, they reinforce a USB device phenomenal. Keyboard, mouse, mobile phone, printer, scanner. All signals arrive. One can put together such a repeater even what I had always done in shorter versions of 5 meters. Also through 2 repeaters together that the sound comes through smoothly.
