Why do USB Ports on Motherboards Stop Working? 

Your desktop or laptop’s USB port may not work due to various reasons. Among which dirty USB ports, outdated drivers, changes in power management settings, and faulty drives or ports are some common reasons. Below we have mentioned every possible reason and solution to fix the issue. 

Dirty USB Ports

Dust can be a problem for your USB ports and cables. When dust builds up on the connectors, it can weaken the connection, and sometimes, it won’t stay connected at all. Dust can also get in between the connections and make it hard for electricity to flow properly.

This can lead to problems like slow data transfer, errors when sending information, or even a complete loss of connection. If too much dirt builds up, it can even cause short circuits between the tiny pins inside the USB port, which can damage your USB device or the port itself.

Fix for the issue – Just keep your USB ports clean. You can use a soft brush or canned air or rubbing alcohol to get rid of the dust and debris. This way, you’ll ensure a good and secure connection between your USB port and the device you’re connecting. To prevent dust from coming back, you can also use USB covers to protect your ports.

Outdated Windows and Optional Updates

Outdated versions of Windows might not have the right software (drivers) to make new USB devices work correctly. This can lead to problems with connecting them or getting them to work properly. Sometimes, the fixes for these USB issues come in optional updates for your computer. If you skip installing these updates, you could face problems that have already been solved.

Also, older versions of Windows that are a few years old may have security gaps that can affect how USB devices work. Some USB gadgets might use special features or rules that older Windows versions can’t handle.

To resolve this keep your Windows updated. Make sure your Windows operating system is up to date. You can do this by going to the Windows start menu and typing “Check for updates.” Then, check for any new Windows updates. If there are updates available, go ahead and install them right away. This will help ensure your USB devices work smoothly and keep your computer secure.

Wrong Installation of USB Controllers

When you put the wrong USB controller drivers or ones that don’t match your devices, it can lead to conflicts between drivers. This can cause your USB gadgets to act oddly or stop working altogether.

If your USB controllers aren’t set up correctly, it can slow down how fast data moves or even cause your connection to drop. This can make downloading files take forever, prevent programs from communicating, or make your USB devices disconnect frequently.

To fix this issue – you need to either remove unnecessary drivers in the USB controller section or add the right drivers to get your USB port working again. To do this, go to Device Manager and find the “Universal Serial Bus Controllers” section. There, you’ll see all the drivers for your USB ports.

If you find a driver that doesn’t belong or isn’t needed, right-click on it and choose “Uninstall.” Similarly, if your USB port doesn’t recognize a device you’ve connected, plug in the device, go to “Universal Serial Bus Controllers,” and click “Scan for hardware changes.” This will install the correct driver, and your USB port will go back to working normally.

Misconfigured USB Selective Suspend Power Settings

USB Selective Suspend is like a power-saving feature in Windows. It helps your computer save energy by turning off power to certain USB ports or devices that you’re not using at the moment. This is good because it helps your laptop’s battery last longer.

However, sometimes this feature can cause problems. If there’s a glitch in the system, it might turn off power to USB devices even when they shouldn’t be. This can make your USB stuff not work correctly.

If you’re having constant issues, you should turn off USB Selective Suspend. To do this, choose “Power Options” or type “Edit power plan settings” in the Windows start menu.

Now, you’ll see some settings. Click on “Change advanced power settings.” Then, look for “USB settings” and expand it. Inside, you’ll find “USB Selective Suspend Power Settings.” Under this, there are options for “On battery” and “Plugged in.” If both of these are set to “Enabled,” change them to “Disabled.” This way, your USB ports will always have power, and your devices should work smoothly.

Wrong Driver Updates

Using drivers that aren’t meant for your USB device or your operating system can cause issues. It’s like trying to have a conversation in a language someone doesn’t understand – your computer and USB device might not communicate properly, leading to problems or even making the whole thing stop working. Installing old or incorrect drivers can also create problems because USB technology keeps getting better with new features and upgrades.

To resolve this issue, first, open the Device Manager. You can find it in your computer’s settings or simply search for it in the Windows search bar. Once you’re in the Device Manager, locate the troublesome USB device that’s giving you trouble.

Next, access the device properties by right-clicking on the troublesome USB device and selecting “Properties.”

If there’s a “Roll Back Driver” option in the device’s properties, use it. This will return the driver to a previous version if available, which can sometimes resolve compatibility issues.

If rolling back the driver doesn’t help or if your driver is outdated, you should update it. Select “Update Driver.” This will ensure your USB driver is up-to-date with the latest improvements.

By following these steps, you can make sure your USB devices and your computer speak the same language, keeping everything running smoothly.

Change Power Management Settings

When you enable power-saving settings on your computer and select “Allow the computer to turn off this device to save power,” it can lead to issues with your USB devices. They may either turn off or receive insufficient power. As a result, your connection might become unstable, and your computer may not recognize the device properly.

To resolve this problem, you can adjust these power settings in a few simple steps. First, open the Device Manager on your computer. Look for the “Universal Serial Bus controllers” category and expand it. Next, find the USB device for which you want to change the power settings. Right-click on it, and a menu will appear. Click on “Properties.”

Inside the properties window, navigate to the “Power management settings” tab. Here, you will find the option that says “Allow the computer to turn off this device to save power.” If this option is currently enabled (indicated by a checkmark), you can disable it by clicking on the box to remove the checkmark. 

This change will help ensure that your USB device receives a consistent power supply and maintains a stable connection with your computer.

Bad or Faulty Motherboard

The motherboard of your computer has special chips called USB controllers. These chips are like traffic cops for your USB ports, making sure they work properly. If these chips get damaged or stop working correctly, it can lead to issues with your USB devices. You might see things like devices not being recognized, USB connections dropping randomly, or having trouble setting up connections.

The motherboard also provides power to your USB devices. If there’s damage to the power delivery lines on the motherboard, your USB gadgets may not get enough power, or they might not work at all.

Fixing these issues with the motherboard can be tricky. In most cases, motherboard damage is permanent and can’t be fixed. However, sometimes, if there’s a small problem with a circuit or connection, a professional with soldering skills might be able to repair it. But it’s important to note that attempting these repairs without the right skills can make things worse and potentially damage the USB port or the motherboard itself. So, it’s usually best to leave such repairs to the experts.

Faulty USB Drive or Wire

When a USB power source or cord is damaged, it can lead to both physical and functional issues. Physical damage, like a bent or broken connector, can make it difficult to properly connect the USB device, causing communication problems. Internal circuitry issues can disrupt the flow of data and power, resulting in odd behavior or the device not working correctly.

Similarly, a damaged USB cord can create similar troubles. If the protective covering of the wire is frayed or broken, it can expose the inner wires, causing connectivity problems. Poor manufacturing or flaws in the wire can also result in unreliable data transfer or insufficient power, which can cause the USB device to malfunction or not work at all.

So, how can you address these problems? First, test the USB device or connection with a different USB drive to determine if the issue lies with that particular one. If the problem persists, check if the USB port on your computer is functioning by testing it with another USB device. If the problem is isolated to the USB drive, you might consider formatting it to resolve any software-related issues. 

However, be aware that formatting will erase all data on the drive, so make sure to back up any important files before doing so. If the cord itself is damaged, unfortunately, the only solution is to replace the entire cable.
