n 208 N Troubleshooting Peripherals 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.
