How to Fix the “USB Device Not Recognized” Error
Listed below are 10 USB not detected fixes that you can try to repair a USB device that has decided to stop showing up. You can apply them in the order we present them or use the table above to focus on the fixes that are most likely to deliver the desired results.
Fix 1: Restart Your Computer
Have you tried turning it off and on again? Seriously, have you? If not, then go ahead and restart your computer right now. There’s a chance that the USB error will be gone.
This simple fix is so effective because restarting your computer forces all applications to close, stopping misbehaving applications from running and causing trouble. Important software, such as USB drivers, then automatically reopens once your computer is done booting up, leaving you with a clean slate.
Fix 2: Try a Different USB Port and/or Machine
Broken USB cables and messed-up USB ports are to blame for many issues with USB devices not being recognized properly in Windows 11/10/8/7. The good news is that your computer most likely has more than one USB port, so go ahead and see if it works any better.
If the issue persists, then the next step is to connect the USB device to a different computer to rule out a more serious hardware issue. When troubleshooting an external hard drive, make sure to swap the USB cable you use to connect the hard drive to your computer for a new one.
Fix 3: Run USB Troubleshooter
All recent versions of the Windows operating system come with a useful USB error troubleshooting tool, and you can access it with a few clicks:
- Launch File Explorer (Windows Explorer in Windows 7) and right-click your USB drive.
- Select Properties.
- Switch to the Tools tab and click the Check button.
- Select the Scan and repair drive option.
- Wait for Windows to find and repair any errors.
Fix 4: Uninstall the USB Device
Your USB driver can become corrupted, and the easiest solution to this problem is to uninstall it. You can then restart your computer, and Windows will automatically load the correct driver again. Here’s what you need to do:
- Open the Start menu, type Device Manager in the Search box, and select Device Manager.
- Expand the Disk drives section.
- Right-click on your USB device and select the Uninstall device option.
- Restart your computer.
- Reconnect the uninstalled USB device.
Fix 5: Disable the USB Selective Suspend Setting
To preserve battery power and prolong the lifespan of some USB devices, the Windows operating system is automatically powering them down after they haven’t been in use for a certain amount of time. In some situations, this setting may cause problems with devices not showing up, especially when the last USB device malfunctioned in Windows 11/10/8/7. The good news is that disabling this feature is easy:

Fix 6: Install the Latest Chipset Drivers for Your Motherboard
Just like all other hardware devices, your motherboard requires drivers to work correctly. If you haven’t done so in a while, you should check whether you’re using the latest chipset drivers available by going to the official website of the manufacturer of your motherboard. If a newer chipset driver is available, download it to your computer and install it just like any other driver.
We strongly recommend you avoid various third-party driver finders and driver updaters because many of them are scammy and some are even downright dangerous. The only driver update we can recommend is Intel Driver & Support Assistant.
Fix 7: Install the Latest Windows Updates
From time to time, Microsoft releases hotfixes to patch critical issues. For example, KB976972 fixes problems with moving data over USB from a Windows 7-based computer that has an NVIDIA USB EHCI chipset and at least 4 GB of RAM, while KB974476 ensures that USB devices resume from the USB Selective Suspend state correctly. To install the latest Windows updates:
- Open the Start menu, type Windows Update, and select the Windows Update option.
- Click the Check for Updates button and review available updates.
- Select each update you want to install and then click Install updates.
- Wait until all updates have been installed.
- Restart your computer.
Fix 8: Reinstall USB Controllers
The communication between USB devices and your computer is controlled by the so-called USB controllers, which are kind of like air traffic control specialists, managing the complex flows of data to ensure that it ends up in the right destination. Reinstalling your USB controllers can fix unknown USB device errors by replacing an unstable or corrupted controller with a working one.
- Open the Start menu, type Device Manager in the Search box, and select Device Manager.
- Expand the Universal Serial Bus controllers section.
- Right-click on the USB controller your USB device is connected to and select the Uninstall device option.
- Restart your computer.
- Connect your USB device.
If you don’t know which USB controller to uninstall, then don’t hesitate to get rid of all of them. Once you restart your computer, your USB controllers will automatically install again.
Fix 9: Access the USB Drive from Linux
Instead of wasting hours and hours trying dozens of Windows-specific fixes to regain access to your unrecognized USB drive, it’s much faster to boot into a live Linux environment and attempt to access it from there. If the drive works in Linux but not in Windows, you know that the problem isn’t hardware-related.

How to Recover Lost Data After Fixing the USB Device Not Recognized Error
Have you managed to regain access to your USB device using the methods described above? That’s great! But what if your files are nowhere to be found? In that case, you need to recover them using data recovery software like Disk Drill.
The purpose of Disk Drill is to scan USB flash drives, external hard drives, and other storage devices for files that can’t be accessed from Windows 11/10/8/7 anymore but are still physically on the storage device. As a user, you don’t really need to worry about how Disk Drill works because the entire data recovery process is completely automated and boils down to a few simple steps:
Step 1: Install Disk Drill on your Windows computer
Disk Drill can be downloaded from its official website for free and used to recover up to 500 MB of lost data. If you need to recover more, you need to upgrade to Disk Drill PRO.
Step 2: Scan the USB device
Once you have Disk Drill installed on your computer, you can go ahead and launch it. Then, select your storage device and click the Search for lost data button.
Step 3: Select & recover your files
Using Disk Drill’s scan results filters and preview feature, select the files you want to recover and click the Recover button. Choose a suitable recovery destination and confirm. That’s all there is to it!
How to Prevent the USB Not Recognized Error
They say that an ounce of prevention is worth a pound of cure, and we wholeheartedly agree—especially when it comes to data loss.
As troubling as the USB device not recognized error may be, it’s actually not that difficult to prevent it (or at least greatly reduce the likelihood of it occurring). You just need to follow a few best practices when using your USB devices, including:
- ⏏️ Safely eject your USB devices: All recent versions of the Windows operating systems let you safely eject a removable storage device by left-clicking the Safely Remove Hardware icon in the system tray and selecting the device you want to eject. You should use this feature before you physically disconnect your USB device from your computer to ensure that all read/write processes have a chance to finish properly, otherwise they could cause corruption.
- 💩 Avoid no-name USB devices: USB storage devices have become very affordable, especially if you’re willing to wait for a good discount. As such, it doesn’t really make much sense to buy no-name USB storage devices and risk issues with faulty flash memory chips. If you do end up with a no-name USB device anyway, then you should use a fake USB flash drive detection tool to check if the advertised storage capacity is real.
- 💧 Store your USB devices in proper conditions: Because USB storage devices that rely on flash memory chips don’t have any moving parts, they can withstand a lot of abuse. What they can’t withstand, however, is prolonged exposure to high humidity or heat levels. That’s why you should always store your USB devices in proper conditions.
