Rolling Back Drivers
If you suspect that an update caused the malfunction:
1. Right-click on the device in Device Manager.
2. Click on Properties, and navigate to the Driver tab.
3. Click on Roll Back Driver if available.
USB Power Management Settings
Sometimes, power management settings can interfere with USB device functionality. Disabling USB selective suspend can help.
Step 5: Modify Power Management Settings
- In Device Manager, find the USB Root Hub under Universal Serial Bus controllers.
- Right-click it and select Properties.
- Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
- Repeat this step for all USB Root Hubs listed.
Additional Solutions for USB Mice and Keyboards
If the previous steps have not resolved your issue, consider these additional options:
Step 6: Check for Conflicting Software
Sometimes, third-party software can interfere with USB devices. Booting your computer in Safe Mode can help identify if software is causing the problem.
Step 7: System Restore
If all else fails and the problem arose recently:
1. Type “System Restore” into the Windows search bar.
2. Select a restore point prior to when the mouse or keyboard issue began.
Seeking Professional Help
If you have tried all of the above solutions and your USB mouse and keyboard are still not functioning, it may be time to seek professional help. Here are some options to consider:
Step 8: Contacting Technical Support
If your devices are under warranty, reach out to the manufacturer’s customer support for assistance. They can often guide you through additional troubleshooting steps or arrange for replacements if necessary.
Step 9: Consider Replacement
If your hardware is old or damaged beyond repair, consider investing in a new mouse or keyboard. Research quality brands that are known for durability and performance. Options range from simple, reliable designs to high-tech gaming keyboards and ergonomic mice.
Conclusion
Experiencing issues with a USB mouse or keyboard can be inconvenient and frustrating. By following the steps outlined in this article, you can troubleshoot many common problems and restore functionality to your devices. Remember to start with basic checks, and progressively move to more advanced solutions. Should all else fail, don’t hesitate to seek professional assistance or consider a replacement.
Final Thoughts
In conclusion, understanding the potential causes behind a non-responsive USB mouse and keyboard leads to quicker solutions and less downtime. Stay proactive about maintaining clean connections, updating drivers, and regularly updating your operating system.

What are the common reasons for USB mouse and keyboard failure?
The most common reasons for USB mouse and keyboard failure include hardware issues, software incompatibility, and connection problems. Hardware issues can arise if the devices malfunction due to wear and tear, liquid spills, or physical damage. Additionally, compatibility problems can occur if your operating system doesn’t support the mouse or keyboard, especially if they are older models or require specific drivers.
Connection problems can be as simple as a loose connection or a malfunctioning USB port. Ensure that the USB devices are properly plugged in and try using different ports to rule out any issues. Sometimes, the issue may not lie with the devices themselves but with the system’s recognition of them, which can often be resolved with proper troubleshooting methods.
How can I troubleshoot my USB mouse and keyboard?
To troubleshoot your USB mouse and keyboard, start by checking the physical connections. Make sure that the USB connectors are securely plugged into the ports and, if possible, try connecting them to a different USB port on your computer. If you’re using a USB hub, try connecting the devices directly to the computer to rule out issues with the hub.
If the problem persists, reboot your computer to refresh the system and see if the devices are recognized. You can also try connecting the mouse and keyboard to another computer to determine if they are functioning properly. If they work on another system, the issue may lie with your original computer’s settings or hardware rather than the devices themselves.
What should I do if my USB ports are not working?
If you find that your USB ports are not functioning, there are several steps you can take. First, try restarting your computer, as this can sometimes resolve minor glitches. If that doesn’t help, check if there are any error messages related to the USB ports in the Device Manager. A yellow exclamation mark could indicate a driver issue that needs to be addressed.
Next, you can update or uninstall the USB drivers via Device Manager. Right-click on the USB entry, select “Update driver,” and follow the prompts. If updating doesn’t solve the problem, you might want to uninstall the device and reinstall it. After doing so, reboot your system, and Windows should automatically reinstall the drivers, hopefully restoring functionality to your USB ports.
Could power management settings affect my USB devices?
Yes, power management settings can significantly affect the functionality of your USB devices. Windows has a feature that allows the system to turn off devices to save power, which can inadvertently lead to your mouse and keyboard becoming unresponsive. To check this, you can access the Device Manager and look under the properties of your USB controllers.
In the power management tab, uncheck the option that allows the computer to turn off the device to save power. Once you make this change, apply the settings and restart your computer. This can often resolve issues where devices stop working intermittently due to power management conflicts.
How can I restore missing drivers for my USB devices?
If your USB mouse and keyboard aren’t working due to missing drivers, you can restore them by accessing the Device Manager. Locate the affected devices under the “Mice and other pointing devices” or “Keyboards” sections, right-click on them, and choose “Update driver.” You can allow Windows to search automatically for updated driver software, or you may choose to browse your computer for driver software if you have it saved locally.
If updating does not work, you can also uninstall the drivers. After doing so, restart your computer, and Windows will automatically attempt to reinstall the necessary drivers upon startup. This often resolves issues related to driver corruption or improper installation, restoring functionality to your USB devices.
When should I consider replacing my USB mouse or keyboard?
You should consider replacing your USB mouse or keyboard if you have exhausted all troubleshooting options and the devices remain unresponsive. If the devices do not work on multiple computers, it is likely that the hardware is faulty. Physical damage, excessive wear, and tear, or liquid exposure can also warrant replacement as repairs may not be feasible or cost-effective.
Furthermore, if your USB keyboard or mouse is outdated and lacks features that meet your current needs, upgrading to a newer model can enhance your computing experience. Consider the functionality, ergonomics, and any additional features you may want, such as programmable keys or wireless connectivity, when deciding on a replacement.
