Disconnect the USB device from the port. Inspect the cable and connector for visible damage or fraying. Try connecting the USB device to another computer or using a different USB cable to see if it works. If the device functions properly on another computer or with another cable, the original port may be the issue. If the device still doesn’t work, replace the faulty USB device or cable.

✔️Update or Reinstall USB Drivers

Open Device Manager on your Windows PC. Expand the "Universal Serial Bus controllers" section. Right-click each USB driver and select Update driver to install the latest version.

If updating doesn’t work, right-click the driver again and choose "Uninstall device". After uninstalling, restart your computer—Windows will automatically reinstall the correct drivers. Finally, reconnect your USB device and check if it is recognized.

✔️Restart and Run Windows Troubleshooter

Sometimes USB ports fail due to temporary operating system glitches. Restarting your computer can often clear these minor bugs. If the problem persists, run the Windows Hardware and Devices Troubleshooter:
