Here are some steps to help resolve the issue:

1. Disconnect and Reconnect USB Cable:

   • Disconnect the USB device from your computer.
   • Wait a few seconds and reconnect it firmly to the USB port.
     
     

2. Try a Different USB Port:

   • Connect the USB device to a different USB port on your laptop. Sometimes ports can malfunction, and using another port might solve the problem.

6. Update Windows:

   • Ensure that your Windows is up-to-date with the latest updates, as they may contain important driver updates and bug fixes.
