Connecting a USB Device
Your computer has two USB ports that supports transfer rates up to 12
MB/s for USB 1.1 devices and 480 MB/s for USB 2.0 devices, such as
digital camera, scanner, printer, modem, and mouse.
USB is specified to be an industry standard extension to the PC
architecture. It supports “Plug-and-Play” technology so you can install
and remove USB devices without turning off the computer. With its
multiple connection capability, up to 127 devices can be connected in a
daisy-chain configuration. In addition, you can use a USB hub that
converts a single USB connector into multiple ports where USB devices
can be connected.
To connect a USB device, simply plug the device cable into one of the
USB ports with the USB “converging arrows”
symbol facing up.
