Introduction
The "USB Device Not Recognized" error on Windows 10 or 11 is one of the most common and frustrating issues users encounter. When this error appears, you'll typically see a notification in your system tray stating that "USB Device Not Recognized" or "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it." This problem prevents your computer from accessing external storage devices, peripherals like mice or keyboards, printers, or other USB-connected equipment. The issue can stem from various causes including outdated or corrupted drivers, hardware conflicts, power delivery problems, system file corruption, or physical damage to the device or port. Fortunately, there are multiple troubleshooting methods available to resolve this issue and restore functionality to your USB devices.
Basic Troubleshooting
Before attempting more complex solutions, it's important to rule out simple causes that can often be resolved quickly. These basic troubleshooting steps can save considerable time and effort:
- Try another USB port: USB ports can fail individually while others remain functional. Disconnect your device and try connecting it to different USB ports on your computer. If possible, test both USB 2.0 (typically black) and USB 3.0 (typically blue) ports, as some devices have compatibility issues with certain port types.
- Restart your computer: A simple restart can clear temporary system errors that might be preventing proper USB device recognition. After shutting down, wait approximately 30 seconds before restarting to ensure all components power down completely.
- Test the USB device on another computer: If available, connect the problematic device to another computer. If it works properly on another system, the issue is likely with your computer rather than the device itself. If it fails on multiple computers, the device may be damaged.
- Check for physical damage: Carefully inspect both the USB connector and port for visible damage. Look for bent pins, debris inside the port, or other signs of physical damage. Even minor connection issues can prevent proper device recognition.
- Use a different cable: For devices that connect via a separate cable (such as external hard drives), try using a different USB cable. Cable damage is a surprisingly common cause of connection issues, especially with frequently used or portable devices.
These basic steps resolve a significant percentage of USB recognition issues without requiring more technical intervention. If your device still isn't recognized after trying these methods, proceed to the more advanced solutions below. (ads)
Disable USB Selective Suspend
Windows includes a power-saving feature called USB Selective Suspend that can temporarily disable USB ports to conserve energy. While this feature is beneficial for laptop battery life, it can sometimes cause USB recognition problems. Disabling this feature can resolve persistent connection issues:
Open Control Panel by searching for it in the Windows search bar or right-clicking the Start button and selecting Control Panel.
Navigate to Power Options by either finding it directly in Control Panel or typing "power options" in the Control Panel search box.
Click Change plan settings next to your currently active power plan (usually "Balanced" or "High performance").
(ads)
Click Change advanced power settings to open the detailed power options dialog.
In the dialog box, scroll down and find USB settings in the list. Click the + symbol to expand this category.
Expand USB selective suspend setting and change both "On battery" and "Plugged in" settings to Disabled.
After making this change, disconnect and reconnect your USB device to see if Windows now recognizes it properly. This adjustment prevents Windows from putting USB ports into a low-power state that might prevent proper device detection.
Reinstall WPDmtp.inf Driver
The WPDmtp.inf file contains driver information for Windows Portable Devices Media Transfer Protocol, which handles communications with many USB devices. Reinstalling this driver can resolve recognition issues, especially for storage devices and smartphones:
Open File Explorer by clicking the folder icon in your taskbar or pressing Windows key + E.
Navigate to your system drive (typically Local Disk (C:)), then open the Windows folder, and then the INF folder. Or copy and paste this full path on directory bar C:\Windows\INF.
(ads)
In the INF folder, click in the search box in the upper-right corner and type WPDmtp.inf to locate the WPDmtp.inf file.
Once found, right-click on WPDmtp.inf and select Install from the context menu.
If prompted by User Account Control, click Yes to allow the installation.
After installation completes, restart your computer to apply the changes.
This procedure reinstalls the core drivers that Windows uses to communicate with portable devices, which can resolve communication issues that prevent device recognition.
Update or Reinstall USB Drivers
Driver problems are among the most common causes of USB recognition issues. Outdated, corrupted, or incompatible drivers can prevent Windows from properly identifying and communicating with your USB devices. Here's how to update or reinstall them:
Open Device Manager by right-clicking the Start button and selecting "Device Manager," or by searching for it in the Windows search bar.
In Device Manager, expand the Universal Serial Bus controllers category by clicking the arrow next to it.
Look for entries labeled USB Mass Storage Device, USB Root Hub, or entries with yellow warning icons.
Right-click on each USB controller entry and select Update driver.
Choose Search automatically for drivers to let Windows find and install the appropriate driver.
(ads)
If updating doesn't resolve the issue, right-click the device again, select Uninstall device, and check the box for Delete the driver software for this device if available.
After uninstallation, restart your computer. Windows will automatically attempt to reinstall the necessary drivers during startup.
If you see any devices listed as "Unknown Device" with a yellow exclamation mark, these might be your unrecognized USB devices. Right-click these and follow the same update/uninstall procedure.
For more comprehensive driver updates, you can also visit your computer manufacturer's website or the USB device manufacturer's website to download the latest drivers specifically designed for your hardware and Windows version.
Check BIOS Settings
Some USB recognition issues originate at a deeper system level than Windows itself. The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) contains settings that control fundamental hardware functions, including USB support:
- Restart your computer and enter the BIOS/UEFI setup. This is typically done by pressing a specific key during startup such as F2, F10, F12, Delete, or Esc. The required key is often displayed briefly during boot with a message like "Press [key] to enter setup."
- Once in the BIOS/UEFI interface, navigate using the arrow keys to find sections labeled USB Configuration, Integrated Peripherals, or Advanced Settings. The exact location varies by manufacturer.
- Look for options such as Legacy USB Support, USB 3.0 Support, or XHCI Hand-off and ensure they are Enabled.
- If you find settings for USB Mass Storage Device Support, make sure this is also enabled.
- For laptop users, check for USB Power Delivery or similar options and ensure they're enabled.
- After making any changes, navigate to the Save & Exit section (typically found on the last tab).
- Select the option to Save Changes and Exit, then confirm your choice.
- Allow your computer to restart normally and test your USB device again.
BIOS/UEFI settings control the fundamental hardware functions of your computer, and improper configurations can prevent USB devices from being detected even before Windows starts. This solution is particularly effective for computers that don't recognize any USB devices at all or that have recently had their BIOS updated.
Format as Last Resort
If all other methods fail to resolve the issue with a USB storage device, formatting the drive might be necessary. This approach will erase all data on the device, so it should only be attempted after exhausting other options and backing up any accessible data.
