If you’ve recently upgraded to Windows 10 and now one of your USB devices isn’t working, read on. Whether it’s a USB mouse, keyboard, pen drive, printer, or some other USB device altogether, this guide should resolve your problem.
Note that there are 5 possible solutions here. You may not need to try them all; just start at the top of the list and work your way down.
If the USB device was working before you upgraded to Windows 10, it’s unlikely to be faulty. But coincidences do occur. It’s certainly possible that your device just happened to die right at the same time that you upgraded Windows. So it’s best to rule that possibility out for sure before spending time on more complex troubleshooting.
To check if the USB device is faulty, simply unplug it (‘Eject’ it if it’s a USB storage device) and plug it into another computer. If it works, the device is fine. If it doesn’t, then you’ve isolated the problem! You just need to buy a replacement.
Your laptop’s power supply delivers power to your USB ports. If, for some reason, it fails to do this properly, the devices plugged into those USB ports may stop working. Sometimes, this can be fixed quite simply:
1) Unplug the power supply and charger plug from your laptop
2) Restart your laptop
3) Connect your USB device to the laptop again
4) Plug the power supply back in
In order to save power, by default, Windows switches your USB controllers off when they’re not in use, and switches them back on again when they’re needed. Unfortunately, sometimes this approach doesn’t work as intended, and Windows fails to switch your USB controllers on again.
To rule this out as the cause of your USB woes, just stop Windows from ‘managing’ power to your USB controllers and devices:
1) Open Device Manager (type “Device Manager” in the Windows search field)
2) Expand the Universal Serial Bus controllers branch
3) Double-click the first USB Root Hub device in the list (if you see only one USB Root Hub device, that’s fine)
4) Click the Power Management tab
5) Un-check the Allow the computer to turn off this device to save power checkbox, and click OK.
6) Repeat steps 3-5 for each USB Root Hub device in your list of Universal Serial Bus controllers
Your USB ports not working problem is probably being caused by driver issues. The steps above may resolve it, but if they don’t, or you’re not confident playing around with drivers manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Download and install Driver Easy.
2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to a flagged USB driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
If none of the above methods resolve your problem, your USB ports might be damaged. To find out, you can take your PC to a repair store and ask them to check. If your USB ports are damaged, the repairer should be able to replace them fairly inexpensively.
