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 software 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 a power distribution failure. We recommend you connect the
device directly to your computer without a hub.
❑ If you have disabled the USB ports in the BIOS setup screen, you cannot use any connected USB devices. To enable the
ports, follow the steps and the tip in Disabling Built-in Devices (page 130).
❑ If the use of USB ports is restricted by the USB Access Restriction Setting utility, you cannot use any connected USB
devices. To change the setting, see Restricting USB Access (page 132).
