You can only use it to connect male to male. That means you could use it to connect two computers, if they happened to be 10 cm apart. It won't extend two USB cords.
Remember one end of a USB jack is a dud, because it ends in something else. A Minijack for power, at device. etc.
Or you need Mini USB to Micro USB, but you only have USB to Mini USB and USB to Micro USB.
