<p>A clean hub is provided to wind a USB line on a wheel which is installed in a USB hub, thereby using the USB hub tidily. A clean hub comprises a wheel on which a USB line is rolled, a connector USB and a distribution USB. Because the existing USB hub has a long line, it is unattractive when it is installed at a near place. But a user can neatly use the USB line by winding it on the wheel installed in the USB hub.</p> |
