When a USB device is not recognized by a computer, it can be frustrating and time-consuming to troubleshoot. The error may prevent the user from accessing important files or using necessary peripherals, such as a printer or external hard drive.
Fortunately, there are several potential solutions to fix the USB not recognized error. The first step is to ensure that the USB device is properly connected to the computer and that the cable is not damaged. If the device is still not recognized, updating the USB drivers or reinstalling them may resolve the issue.
In some cases, the USB not recognized error may be caused by a hardware problem, such as a malfunctioning USB port. If this is the case, the user may need to replace the port or seek professional repair services. By following these steps and troubleshooting methods, users can regain access to their USB devices and avoid further frustration.
Check USB Connections
One of the most common reasons for the “USB not recognized” error is a loose or faulty connection. To check the connection, follow these steps:
- Disconnect the USB device from the computer and wait for a few seconds.
- Inspect the USB cable for any visible damage, such as frayed wires or bent pins.
- Plug the USB device back into the computer and make sure it is securely connected.
- If the USB device has its own power supply, make sure it is plugged in and turned on.
If the USB device is still not recognized, try connecting it to a different USB port on the computer. Sometimes, certain USB ports may not be functioning properly.
If these steps do not resolve the issue, it may be necessary to update the USB drivers on the computer or to try the USB device on a different computer to determine if the issue is with the device or the computer.
Update USB Drivers
One of the most common reasons for the “USB not recognized” error is outdated or corrupted USB drivers. Updating the drivers can help fix the issue. Here are the steps to update USB drivers:
Step 1: Press the Windows key + X and select Device Manager from the menu.
Step 2: Locate the Universal Serial Bus controllers option and expand it.
Step 3: Right-click on the USB driver that is causing the issue and select Update driver.
Step 4: Select Search automatically for updated driver software option and wait for the process to complete.
Step 5: Restart the computer and check if the USB not recognized error has been fixed.
Alternatively, you can also download the latest USB drivers from the manufacturer’s website and install them manually. Make sure to download the correct drivers for your specific USB device and operating system.
Updating USB drivers can be a simple and effective solution for fixing the “USB not recognized” error. If the issue persists, try other troubleshooting methods such as checking for hardware issues or reinstalling USB controllers.
Restart the Computer
If the USB device is still not recognized, restarting the computer may help resolve the issue. This simple step can help reset the USB ports and drivers, potentially fixing any software glitches that may have caused the problem.
To restart the computer, click on the “Start” button and select “Restart” from the options. Alternatively, press the “Ctrl,” “Alt,” and “Delete” keys together and select “Restart” from the options. Once the computer restarts, try plugging in the USB device again and see if it is recognized by the computer.
If the USB device is still not recognized after restarting the computer, try plugging it into a different USB port. This can help rule out any issues with the specific USB port that was previously being used. If the device is still not recognized, move on to the next troubleshooting step.
Disable USB Selective Suspend
Another potential solution to the “USB not recognized” error is to disable USB selective suspend. This feature allows the computer to conserve power by turning off USB devices that are not in use. However, it can sometimes cause issues with certain devices.
To disable USB selective suspend, follow these steps:
- Open the Control Panel.
- Click on “Power Options.”
- Click on “Change plan settings” next to the power plan you are currently using.
- Click on “Change advanced power settings.”
- Scroll down to “USB settings” and click on the “+” next to it to expand the options.
- Click on “USB selective suspend setting” and change the setting to “Disabled.”
- Click “Apply” and then “OK.”
After disabling USB selective suspend, restart the computer and see if the “USB not recognized” error has been resolved.
Note that disabling USB selective suspend may cause the computer to consume more power, so it is not recommended to leave it disabled unless necessary.
Uninstall and Reinstall USB Controllers
One of the most effective ways to fix the USB not recognized error is to uninstall and reinstall the USB controllers. This process involves removing the USB controllers from the Device Manager and then restarting your computer to reinstall them automatically. Here’s how to do it:
Step 1: Press the Windows key + R to open the Run dialog box. Type “devmgmt.msc” and press Enter to open the Device Manager.
Step 2: Expand the “Universal Serial Bus controllers” section to see a list of all the USB controllers installed on your computer.
Step 3: Right-click on the first USB controller and select “Uninstall device”. Repeat this step for all the USB controllers listed under “Universal Serial Bus controllers”.
Step 4: Restart your computer. Windows will automatically reinstall the USB controllers you uninstalled in the previous step.
Step 5: Check if the USB not recognized error is fixed. If not, repeat the process for all the USB controllers listed in the Device Manager.
Uninstalling and reinstalling USB controllers can help fix any issues caused by corrupted or outdated drivers. It is a simple and effective solution that can save you a lot of time and frustration.
Check for Windows Updates
One of the reasons why USB devices may not be recognized by a computer is due to outdated drivers or software. To fix this issue, users can check for Windows updates to ensure that their system is up to date.
To check for updates, users can follow these steps:
- Click on the Start menu and select Settings.
- Select Update & Security.
- Click on Check for updates.
If updates are available, users should download and install them. This will ensure that their system has the latest software and drivers, which can help resolve the USB not recognized error.
It is also important to note that some USB devices may require specific drivers to function properly. In such cases, users should visit the manufacturer’s website to download and install the necessary drivers for their device.
Check for Hardware Issues
When a USB device is not recognized, it could be due to hardware issues. Here are some steps to check for hardware issues:
Step 1: Check the USB port. Sometimes, the USB port may be damaged or not working properly. Try plugging the USB device into a different USB port and see if it is recognized.
Step 2: Check the USB cable. The USB cable may be damaged or not working properly. Try using a different USB cable and see if it is recognized.
Step 3: Check the USB device. The USB device may be damaged or not working properly. Try using the USB device on a different computer and see if it is recognized.
Step 4: Check the USB driver. The USB driver may be outdated or not installed properly. Go to the device manager and check if there are any issues with the USB driver. If there are issues, try updating or reinstalling the driver.
