Connecting a Universal Serial Bus (USB) Device
You can connect USB devices such as an external mouse, keyboard, speaker, and 
microphone to your computer.
To connect a USB device
Locate the USB device identified by the symbol. Plug one end of the USB 
cable into this port and the other end into the USB device.
You can use an optional Sony USB mouse PCGA-UMS1 series (not supplied) 
with this computer. Since the USB mouse software driver is preinstalled in the 
computer, you simply plug the USB mouse into the USB connector to use it. One 
USB connector supports one USB device. 
Before you connect or disconnect a mouse, turn off the computer.
The following steps describe the procedure for connecting a USB mouse to your 
computer. Use the same procedure for connecting all USB devices.
