What should I do if I cannot connect a USB device?
If applicable, check the USB device is switched on and using its own power supply. For example, if you are using a digital
camera, check the battery is charged. If you are using a printer, check the power cable is connected properly to the AC outlet.
Try using a different USB port on your computer. The driver could be installed to the specific port you used the first time you
connected the device.
Check the manual provided with the USB device. You may need to install software before you connect the device.
Try connecting a simple, low-powered device such as a mouse to test that 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.
