What to do if my Dell Monitor USB interface is not working?

If the USB interface on your Dell monitor isn't working, check that the monitor is turned on. Reconnect the upstream cable to your computer and reconnect the USB peripherals (downstream connector). Try switching the monitor off and then on again, and reboot your computer. Some USB devices, like external portable HDDs, require higher electric current, so connect the device directly to the computer system.
