The specifications of a USB states that the maximum length of a USB cable is 5 meters [16 feet). As a result, you cannot extend the distance of your USB device to more than 16 feet without using a USB "active" extension cable lalso known as a USB repeater cablel.

This cable contains active electronics that boost the USB signal for maximum reliability and performance over extended distances. Up to 4 of these USB Active Extension cables can be linked to extend the distance between your computer and your USB peripheral to up to 80 feet.
