Due to its design, USB cable has a normal maximum length of about 5 meters ( 16.4 feet), but you can get longer distances by using an active USB extension cable from Monoprice. This is a bus-powered extension cable that can be used to increase the length of a device without any signal loss or potential performance problems. It contains active electronics, which boost the USB signal for maximum reliability and performance over extended distances. The cable can be operated as self-powered extender, for use with USB cameras printers webcams keyboard/mouse, etc.
The optional application of DC power (via the DC power jack, use PID 2220) is designed for devices which need much power, such as USB hard drives, active hubs, high-power wifi networking devices etc. It is a true plug-and-play device. No additional drivers are required. It supports Windows 98/2000/XP/Vista/7, Mac OS X v 10.0 or higher, and Linux. It can also be used with many types of USB devices, including the Xbox Kinect and the Eye of the PS3 Move.
