How To Fix USB Connectivity Problems


USB ports are a convenient way to connect an external hardware to your computer or laptop. From flash drives to external hard drives, optical drives to HDMI cables, lots of components are connected using USB ports. While usually there aren’t many problems that you would encounter with USB ports, yet there may be some from time to time.

The most common of all USB problems is the port not recognizing any device. It may so happen when you have repeatedly inserted and removed a device. This renders the port to be inactive and it would not recognize any device. There is nothing or may not be anything wrong with your external hardware or device. It may simply be a case that the USB port has been shut off.

Here are the answers to how to fix USB connectivity problems.

  • You should go to the device manager in your system and scan for hardware changes. When you do this, the device manager would scan for all hardware and all recent changes that have happened. In many cases, this scanning for hardware changes can fix the problem. The USB port may open up again and you can easily connect any device that is compatible. You can check this by inserting the USB device. At times, restarting can help because any restoring of settings or hardware changes usually takes a restart to be fully effected.
  • If scanning for hardware changes and restarting the computer subsequently doesn’t help then you should again open the device manager, look for the USB controller corresponding to the port that has connectivity problems, disable it and then enable it again. This re-enabling of the USB controller should solve the problem and you should be able to use your USB devices again.

In case you are unaware of which USB controller to disable and enable, you can refer to your system manual or you can run a trial to see which USB controllers correspond to which ports. You can do this by disabling one USB controller and checking all the ports to find out which has been disabled and then enable it again.

In some cases, USB connectivity problems would not pertain to the functioning of the port but the speed with which data is being shared or the efficiency with which a specific device is running. In such scenario, you should update your USB drivers.
