(Solved) USB Ports Not Working in Windows 10 Fix


Why Are USB Port Not Working

Case – USB Ports Not Working

Hi there, do you know how to make a USB, an external hard drive, or an SD card to show up on PC when the USB port is not working? I tried to connect my device to other USB ports on my PC, but still, nothing showed up.

How can I  repair a not working USB port and make storage devices detectable on Windows 10? Help please.

When a USB port fails to work or stops working, Windows PCs or laptops won’t be able to read or detect these external storage devices. To make the USB port work again in Windows 11/10/8/7, you should check out the causes first.

What Causes USB Ports Malfunctioning

Here is a list of possible causes of USB Port not working issues:

  • Power surge on the USB port
  • USB port driver is updated
  • USB connection cable is broken
  • USB port is faulty or broken

Note that the basic way is to restart your computer and change the USB cable. If these don’t work, don’t worry. Follow the below guide to effectively repair not working USB ports and make external storage devices detectable again without losing any data now.

Laptop users

In some situations, when a laptop switches from battery to power cord, how the power supply delivers power to the USB ports may stop working. To verify this is not the problem, follow the steps below.

  1. Unplug the USB devices and power cable from the laptop.
  2. Leaving all the cables disconnected, restart the computer.
  3. Once back in Windows plug in your USB devices.
  4. Finally, plug in your power cable again.

If the steps above have not helped and you have a laptop with a removable battery, follow the steps below.

  1. Shut down the computer.
  1. Disconnect the power cable and removed the battery.
  1. Wait five minutes to perform a hard reset. After this is done, insert the battery back into the laptop, reconnect the power cable, and turn the computer back on.

How do you get lint off a charging port?

To be safe, back up your iPhone or iPad to your computer or the cloud. Power it off, and with a normal toothpick, gently remove the lint. You will be amazed how much can get stuck in the port. Connect the charger and see if it works.

Try Plugging Into a Different Computer Or USB Port

Unplug the USB stick from the current port and computer, and try plugging into a different computer and/or USB port. If it works on the new USB port or computer, the USB port may be damaged or dead, or the computer itself may have a problem.

A faulty, damaged or dead USB port presents problems such as failure to detect USB drives or displays error messages. Check if the port is clean, dust-free, and firm. If it’s moving up and down or feels loose, then it’s faulty/damaged.

If you’re using a USB hub, unplug the stick from the hub and plug it directly into your computer. Some hubs have insufficient power for external drives to function, which may be the case with yours.

If the USB drive isn’t showing up even after trying a different port, computer, or checking in Disk Management, the drive is probably dead and needs to be replaced.

Check CMOS

With older computers (2010 and earlier), it may be necessary to enable USB in CMOS. If present, make sure USB is enabled or set to legacy and is not disabled in CMOS setup.


You must use administrative credentials to log on to Windows to perform some of the troubleshooting methods that are listed in this article. If this is your personal computer, you are likely already logged on with an administrator account. If this is a computer that is part of a network at work, you might have to ask the system administrator for help.

If the cable doesn’t seem to be the problem, check the wall plug adapter – especially if it’s one where the charging cable can be removed. We’ve encountered issues in multiple chargers where the USB port becomes a little loose after endlessly plugging in and unplugging the cable.

Also, check whether the same charger/cable combination works on a different device because this will help you eliminate the possibility that it is your device at fault, rather than the cable or charger. You should also make sure there isn’t a problem with your wall socket.

It’s also important to check if the combination of charger and cable is compatible with the phone in question, which helps rule out the smartphone as the cause of the problem. In the case of the charger, some models offer combinations of voltage and amperage for specific models, which can cause the charger to not charge the cell phone battery, and even if it does, it happens at a very slow rate. 

Solution 1: Checking the Power Supply

Keep in mind that this solution only applies to laptop users. So, if you’re using a desktop computer, proceed to the next method. It is worth noting that your USB ports will function properly if they get the right power supply. So, we recommend performing the following troubleshooting steps:

  1. Unplug your laptop from the power supply.
  2. Restart your computer.
  3. Try plugging your USB device to your laptop.
  4. Connect your PC to the power supply again.

Solution 3: Checking the Power Management Settings

By default, your system switches the USB controllers off when they are not in use. Windows does this to save power, but it automatically switches them back on when you need them. However, there are some technical glitches that prevent your system from performing this task properly. So, you need to stop your system from ‘managing’ the power settings for your USB devices and controllers. To do that, follow the steps below:

  1. On your keyboard, press Windows Key+X.
  2. Select Device Manager from the list.
  3. Look for Universal Serial Bus Controllers, then expand its contents.
  4. On the list, double-click the first USB Root Hub device.
  5. Go to the Power Management tab.
  6. Deselect the ‘Allow the computer to turn off this device to save power’ option.Click OK to save the changes.
  7. Click OK to save the changes.
  8. If there are multiple USB Root Hub devices under the Universal Serial Bus Controllers list, you have to repeat steps 3 to 5 for every device.

Create a New Drive Volume Assign a Drive Letter

If your device appeared in the Disk Management step, you can create a new drive volume and assign a drive letter. The Disk Management tool fixes partitioning and file system problems with different drives.

However, your USB stick may show only Unallocated space, in which case you’ll have to create a new partition so that Windows and other operating systems can use it.

  • Right-click Start>Disk Management, right-click on the Unallocated space>New Simple Volume and follow the prompts to create a partition.

If you still can’t see your flash drive, yet it’s partitioned, make sure it has a drive letter. Ideally, this should be automatic, but if you removed it manually, the drive won’t be detected or accessed in Windows.

  • Right-click the drive’s partition and click Change Drive Letter and Paths.
  • If it doesn’t have an assigned drive letter, click Add and pick a letter. If it has a letter, click Change and choose a different one.

How to Recover Data/Files from a USB Flash Drive

If your pen stick is damaged beyond repair, you may have to concentrate only on recovering the data. Some conditions that can make your gadget dead include damaged circuit board (blown resistors/capacitors, lifted pads, damaged NANDs, and broken crystal oscillator), damaged controller chip, and unresponsive drive.

Recovering data from a flash disk is a complicated task. You may have to a hire an expert to do the job for you, but read the following steps to see if you can do it own your own.

  1. Get recovery software and a NAND reader that supports the drive’s controller type. Look on the controller chip to know the exact type, but be careful when examining the chip to avoid damaging the PCB board and NAND.
  2. Carefully separate the NANDs from the PCB using a precision soldering iron.
  3. Place the NANDs on the data recovering tool, which consists of NANDs readers, and you will be able to recover the files.

2. Check Power Supply (for laptop users)

Sometimes, the power supply fails to supply the power to USB ports. This can result in USB ports to stop working. Follow this method to fix this issue.

Step 1. Unplug your laptop’s power supply, along with the charger plug.

Step 2. Now, restart the laptop.


Step 3. Reconnect the USB device to the USB port of your laptop.

Step 4. Plug charger and power supply back on your laptop.

This should fix the problem. If you are still facing the same issue, follow the next method.

Method 3 Restart Disconnect USB Devices

The next thing you can try is to disconnect all USB devices and then restart the machine. once you have restarted, try to connect the USB device that was causing the problem.

If that particular USB port doesn’t recognize it, try another one. If the device is recognized by a different USB port, there could be a hardware problem with one of the USB ports. If no USB port recognizes the device, then keep reading because it’s probably something else.

Recover Data from Inaccessible USB Drive after USB Port Not Working Repair

In general, the above 8 fixes can help you get rid of USB port not working issue. However, if you still can’t access the drive to use the data on it, you will need to recover data on it.

Here, you can use this free data recovery software – MiniTool Power Data Recovery to do that job since this software can recover both existing and deleted files from different digital data storage devices like hard drives, memory cards, USB drives, and more.

The Removable Disk Drive feature of this software can be used to recover files from the USB drives. Besides, with the Trial Edition, you can go to check whether it can find the files you want to recover and then decide to get a full one or not.

Now you can click on the following button to download and install the Trial Edition on your computer to have a try.

Step 1: Connect the USB drive to the computer and open the software. You will enter This PC interface directly. Then, you need to choose Removable Disk Drive module from the left list.

After that, the connected USB drive will be shown on the software interface. Just choose that USB drive and click on the Scan button to continue.

Note: If the USB drive is not displayed here and you are unable to see it on the Disk Management, the drive should be physically damaged. Unfortunately, there will be no way to recover data on it.

Step 2: The software will begin to scan the USB drive. When the scanning process ends, you will see the scan result interface.

The scanned files are listed by path by default. You can open each path to find the files you want to recover.

If there are so many scanned files and it is difficult to find the needed items, you can use the Type, Find, and Filter features to locate the files you need to restore quickly.

Step 3: After choosing the needed files, it’s time for you to save them. However, you are not allowed to save files with the Trial Edition, thus, you need to update it to an advanced edition to keep your files successfully.

Other Possible Solutions

If nothing has worked until this point, it’s pretty safe to say there could be a problem with the actual hardware. The best thing to do is to connect the device to another computer and see if it works or not. If not, then it’s definitely an issue with the device.

Possible Solution #1 – The other possible solutions are to try a different USB cable, if you have one lying around. If not, just buy a new cheap USB cable from Amazon: A to B, A to Micro B, A to Mini B, or A to A. This is a fairly rare problem, but I have seen it occur a few times over my many years doing technical support.

Possible Solution # 2 – Another possible solution is to take the device, connect it to another machine and if it does recognize the device properly, to then eject it properly from that computer before reconnecting it to the original computer. I’ve seen this problem occur with several flash drives that were unplugged without ejecting properly. After connecting them to another computer and ejecting them properly from there, they suddenly started to show up on the original computer that was not recognizing them.

Possible Solution #3 – A few people have had luck getting rid of this problem by updating the BIOS. I’ve already written an article about whether it’s a good idea or not to update the BIOS, but in this case, it might be worth a try. You can also go into the BIOS and disable USB, restart the computer and then enable USB again. The only thing you need to make sure is that you have a PS2 port on your computer, otherwise you won’t be able to do anything once you disable USB in the BIOS if your keyboard and mouse are connected via USB.

Hopefully, one of the many solutions above will solve your USB problem. If not, post a comment and I’ll try to help. Enjoy!
