What should I do if my VAIO computer does not recognize the USB device?

• 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.
