Per the text, there are several steps one should follow when
investigating a problem with a USB port. Identify two (2) issues that
you believe are the most common among general USB problems. Justify your
USB port issues are either device related,port related or driver related.
Port related issues arise when the connectors are not inserted properly or are not functioning properly which will be indicated to the user in the form of popups or a visual alert when they are inserted.
The issue can be resolved by going to Control Panel>System and Maintenance>Device Manager
There double click USB controllers and check if controllers are working properly or not.
If the alert persists then its most probably a driver issue which is the second most common issue with USB controllers.
Updating the device drivers from the device icon in the connected devices list ,right click and select update drivers to manually update the device drivers from the manufacturers website and check if the device works properly again.
If the device still does not work properly try uninstalling its software,unplugging device.Plug it in again after 20 seconds and install its software again accirding to the manifacturers instructions.
