Certain monitors from manufacturers such as Dell, ASUS and HP feature two or more USB ports that you can use to connect your USB devices. These USB ports, however, do not work unless you connect your monitor to your computer using a Type-A male to Type-B male USB upstream cable. Monitors that feature USB ports usually include a USB upstream cable as part of the product packaging.
Turn off your computer, and then locate the square-shaped Type-B USB port on your monitor. Usually, you can find the port near the location where you connect the power, VGA, DVI or HDMI cables.
Connect the Type-B end of the USB cable into the Type-B USB port on your monitor, and then connect the other rectangle-shaped Type-A end of the cable into a vacant USB port on your computer. You can find USB ports on the front or back of the CPU case.
Turn on your computer, then connect a USB device to your monitor. If you computer doesn't detect the USB device, install the drivers for your monitor from the disc provided by your manufacturer, or download them from the manufacturer’s website.
