9 USB and 1394 Devices What Is USB? USB (Universal Serial Bus) is a hardware interface that can be used to connect an external device such as a USB keyboard, mouse, drive, printer, scanner, or hub to the notebook or an optional docking device. A hub is a connecting device that can be either powered or unpowered. USB hubs can be connected to a USB port on the notebook or to other USB hubs. Hubs support varying numbers of USB devices and are used to increase the number of USB devices in the system. ✎ Powered hubs must be connected to external power. Unpowered hubs must be connected either to a USB port on the notebook or to a port on a powered hub. A USB device may require support software, which is usually included along with installation instructions, with the device. The 4 USB ports on the notebook support USB 2.0-compliant, USB 1.1-compliant, and USB 1.0-compliant devices. Hardware and Software Guide 9-1
