Is your USB port not working?


USB port not working?

Is the USB port not working? The following steps will help you quickly identify and resolve the issue as quickly as possible.

Has the USB port on your laptop or PC stopped working? This problem needs to be diagnosed and fixed at its root.

And here’s what you need to know to get your USB ports working again quickly.

You think your USB port doesn’t work? Try it!

Firstly be sure that the problem is with the port, not the device you’re connecting.

And then you’ll need to know how to troubleshoot the USB port if you want to figure out what the problem is. It’s just a test of the USB port.

So connect the device to another USB port.

When it does not work, then you have a faulty device; when it does work, you have a problem with the first port.

(Note that if you cannot reformat the USB drive, you will have to replace it.)

In other words, one of these things will let you know if your USB port is broken:

  1. The device cannot be detected.
  2. The operating system displays an error message related to the device (replacing the device might resolve this).

Also it is important to check the state of the USB port either way. Is there any damage to it? Turning off your PC or laptop is the best way to check.

And the next thing you should check is the USB port.

Is it dust-free and clean? There’s a possibility that dirt, dust, and other detritus have become embedded in the port.

To clarify, Both laptops and desktop computers are susceptible to this problem.

And the dust on your system will reduce airflow, resulting in overheating.

This is particularly damaging to laptops, whose performance can be reduced in seconds by overheating.

But you can fix this by blowing compressed air into the USB port. You might also find a vacuum cleaner useful here.

Last but not least, wiggle your USB cable (or flash drive, if you have one).

If the drive is moving and feels loose—typically going up and down—then there’s a problem.

Fixing faulty USB hardware

A few software solutions will follow, but first, how do we fix a loose USB port?

A USB port is soldered to a board inside your computer.

The motherboard may be here, but the secondary printed circuit board (PCB) typically is.

In regular use, ports can become movable, at times completely detached.

Often, this is caused by the shape of the connected USB devices.

Wi-Fi, Bluetooth, and even new USB flash memory are unlikely to put any significant stress on the port’s physical connection, but older “stick” memory drives are another matter.

The same holds true for USB cables; their size and associated weight act like a lever, causing USB ports to become loose.

It is not easy to replace the USB port on the motherboard if you suspect it is faulty.

You may be able to find a replacement board for a desktop computer that can be inserted easily.

Need to fix the USB port on your laptop? Soldering iron is required.

Of course, you can take this to an expert for repair, but there will be associated costs.

But if you want to do it yourself, be sure you know how to solder.

So check out the software fixes first if you are unsure.

Can Restarting a Computer Fix Broken USB Ports?

Are you able to turn it off and on again?”

It’s a well-known tech support standby for a reason: it works!

Restart your computer after inserting your unrecognized USB device into the suspect USB port.

And after the operating system has rebooted, the USB device should be detected.

Otherwise, you should find out what the device does in the Windows device manager.

In Windows 10, you can check USB ports through the Device Manager

Firstly, Navigate to Device Manager by right-clicking the Start button.

Device Manager displays all the devices attached to your computer, grouped into categories.

The list is ordered alphabetically, so you’ll find Universal Serial Bus controllers at the end.

Subsequently look for the USB Host Controller in the list.

You may find the device has a longer title, but it will feature those three words.

Doesn’t your computer have a USB host controller? This may explain why your USB device isn’t working.

The fix is to click on the button on the toolbar that says Scan for hardware changes.

It will start checking all connected hardware and in most cases will detect the USB port and anything connected to it.

But if this does not work, you should consider reinstalling the USB host controllers.

Click on each USB Host Controller item in turn and select Uninstall.

And after they’re uninstalled, reboot your computer.

After Windows restarts, USB Host Controllers will be reinstalled automatically.

And this “refresh” can help fix USB port problems.

Note: While the USB Host Controllers are being uninstalled, your USB mouse and keyboard will be disabled.

Are Your USB Ports Not Working Because of Power Settings?

Detection of USB devices will be affected if power management settings are overriding your USB controller.

There will appear to be a problem with USB, but in fact the operating system has put the device to sleep.

You should do this if your laptop’s USB port does not work.

If you want to save power, you might have set your Windows 10 desktop to low power.

USB Selective Suspend is a power saving setting that limits the power to USB devices, reducing battery usage.

It works well most of the time, but sometimes it looks like you have a problem with your USB ports.

Open the Windows Control Panel and adjust the settings.

  1. Go to the control panel by clicking Start.
  2. Choose the corresponding result.
  3. Choose Hardware and Sound > Power Options.
  4. Then click Change plan settings > Change advanced power options for the selected plan.
  5. Locate USB Settings and expand to find USB suspend settings.
  6. Disable the drop-down menu.
  7. To confirm, click Apply and OK.
  8. Restart your PC to ensure this change takes effect.

The USB ports that were not working should now be working.

(While Windows 10 has largely abandoned the Control Panel, it can still be accessed for some tasks, like power settings.)

You have fixed your broken USB port!

To sum up, You have several options for repairing an unresponsive USB port, as you can see.

So you can usually fix it if it’s not dead.

When your USB port isn’t working, you should:

  1. Perform a physical examination.
  2. If necessary, make physical repairs to the port.
  3. Restart Windows.
  4. Uninstall the USB Host Controller in Device Manager.
  5. Turn off USB Selective Suspend power saving.

Your computer’s USB ports aren’t the only weak spot.

If you know how to test your PC for failing hardware, you can save a lot of money if you take care of your hardware.
