What should I do if I cannot connect a USB device?
❑ If applicable, check the USB device is turned on and using its own power supply. For example, 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 the
AC outlet.
❑ Try using another USB port on your computer. The driver could be installed to the specific port you used the first time you
connected the device.
❑ See the manual that came with your USB device for more information. You may need to install software before you connect
the device.
❑ Try connecting a simple, low-powered device such as a mouse to test if the port is working at all.
❑ USB hubs may prevent a device from working because of the distribution of power. We recommend you connect the
device directly to your computer without a hub.
❑ If you have restricted the use of USB ports with the USB Access Restriction Setting utility, you cannot use any USB
devices connected to the USB ports on your computer. To change the setting, see Restricting USB Access (page 139) .
