Default Power surge on USB Port - Windows 10


After the latest Windows update I am getting an error, after plugging an AOC portable monitor with DisplayLink software in, that states, "Power surge on USB port": Unknown USB Device needs more power than the port can supply". This happened immediately after the latest Windows 10 update. It's definitely not the machine because I also tried another laptop that I also use the monitor for that has the same update and get the same error. I tried going into the device manager to uninstall the USB hub and root hub, restarted the laptop to re-install the USB software but I get the same error after plugging the USB monitor in. Has this been a common problem? Is there a solution for it?
