Unfortunately, today you plugged in your beloved USB into your computer, and it shows the 'USB device not recognized' error. What's noteworthy is that the USB is either brand new or hasn't been used for long, and it's already encountering the USB device not recognized error. So, how do you resolve the 'USB device not recognized' error? As you may know, USB devices are not flawless, often plagued with issues like unformattable USB or even failure to open. Mytour has provided detailed guides on fixing issues like unformattable USB or devices not opening in previous articles. However, dealing with the 'USB device not recognized' error on Windows 10/ 8/ 7 is a different challenge.
The 'USB device not recognized' error on Windows 10/ 8/ 7 prevents you from connecting to your computer, among other possible issues. Due to numerous reasons leading to the 'USB device not recognized' error on Windows 10/ 8/ 7, you can self-diagnose the USB Device Not Recognized error on your computer or refer to our article below for guidance.
Fixing the 'USB device not recognized' error on Windows 10/ 8/ 7.
Method 1: Update Device Driver
If Windows doesn't recognize the device, in the Device Manager window, you may see the device listed as Unknown Device.
To open Device Manager, click on Start, then type devmgmt.msc into the Search box or access Control Panel, find and click on Device Manager.
In this scenario, right-click on Unknown Device, select Properties, then choose the Driver tab and click on Update Driver.
If this option doesn't work, you can try downloading the device driver from the manufacturer's official website.
If your USB device is a Flash drive, the cause might not be a driver issue. However, if you're installing a printer, connecting a drawing pad, or similar devices through the USB port, the problem could be a faulty driver you downloaded for a specific device.
Method 2: Restart and Disconnect USB Devices
Another solution you can try to fix the issue is to disconnect all USB devices and restart your computer. Once the computer restarts, try reconnecting the problematic USB device.
If one USB port doesn't recognize the device, try plugging it into another port. If other USB ports still recognize the USB device, the issue may be with the faulty hardware of that specific USB port. If no USB port recognizes the device, you can try applying the next solutions.
Method 3: USB Root Hub
Additionally, you can try another solution by opening Device Manager, expanding USB Serial Bus Controllers, right-clicking on USB Root Hub, and selecting Properties.
Click on the Power Management tab, check the box for Allow the computer to turn off this device to save power. If there are multiple USB Root Hubs, you need to repeat these steps for each hub.
Click OK and restart your computer. Try reconnecting the USB device and check if it's recognized.
If not, go back to the Power Management tab for each USB Root Hub, check the box for Allow the computer to turn off this device to save power once again. If the device is still not recognized, uncheck the box.
Method 4: Direct Connection to the Computer
In some cases, the culprit causing the USB Device Not Recognized error could be a USB hub. Due to a limited number of USB ports, using a hub is necessary. To fix the error, disconnect the hub and directly connect the device to a USB port on the computer. Then, consider purchasing a higher-quality hub for future use.
If using a different hub still results in an error, the only solution may be to accept reducing the number of connected devices to match the actual available ports.
