External Device Connections Connecting a USB Device USB (Universal Serial Bus) is a hardware interface that can be used to connect external devices such as a USB keyboard, mouse, drive, printer, scanner, or hub to the notebook or an optional port replicator. A hub is a connecting device that can be powered or unpowered. USB hubs can be connected to a USB connector on the notebook or on an optional port replicator or to other USB devices. 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 connector on the notebook or to a port on a powered hub. The USB connectors support USB 2.0 and earlier devices. Some USB devices may require additional support software, which is usually included with the device. For more information and software installation instructions, refer to the documentation included with the device. Identifying the 2 USB connectors on the notebook 6-2 Hardware Guide
