Check if the USB device is on and using its own power supply.

• If you are using a digital camera, check if the battery is charged.

• If you are using a printer, check if the power cable is connected properly to an AC outlet.

You may need to install a USB driver for the USB device before connecting the device. Refer to the manual that came with the USB device for more information.

Try using another USB port on your VAIO computer. The USB driver could be installed to the specific port you used the first time you connected the device.

USB hubs may prevent the USB device from working because of a power distribution failure. We recommend you connect the device directly to your VAIO computer without a hub.

Check if a USB storage device is available.

The USB ports are disabled if Disabled is selected for the USB ports in the BIOS setup screen. In such a case, change the BIOS setting. See Restricting the Use of Built-in Devices for more information.
