1. Possible causes
1. USB flash drive failure: The USB flash drive itself may have problems, such as interface damage, internal memory chip failure, etc.
2. Driver problem: The USB driver of the computer may not be installed correctly or corrupted, resulting in the computer not recognizing the USB flash drive.
3. USB interface problem: The USB port of the computer may be physically damaged, or it may be in poor contact due to long-term use.
4. System Setup Issues: Some settings on your computer may prevent the USB flash drive from being displayed, such as the USB device being disabled or hidden.
5. Operating system issues: Some errors or conflicts in the operating system may also cause the USB flash drive to not display properly.
Second, the solution
1. Check the USB flash drive:
Try plugging the USB flash drive into another computer to see if it is recognized. If it can't, it could be a problem with the USB flash drive itself.
Use a USB flash drive repair tool to try to repair the USB flash drive, or contact the manufacturer for repair or replacement.
2. Update or reinstall the USB driver:
Open Device Manager (in Windows, you can do this by right-clicking on "This PC" or "Computer", then selecting "Manage", and then clicking on "Device Manager").
Locate Universal Serial Bus Controller in Device Manager and expand it to see if there are any unknown devices or devices with a yellow exclamation mark.
If so, right-click on the device, select "Update Driver" or "Uninstall Device", then restart your computer to have the driver reinstall automatically.
3. Check the USB port:
Try plugging the USB flash drive into another USB port of your computer to see if it can be recognized properly.
If none of the interfaces are recognized, consider using a USB hub or adapter to try.
Check for dust or foreign objects inside the interface, and if so, use a soft brush or hair dryer to clean up.
4. Check the system settings:
Make sure that the USB device is not disabled in your computer's BIOS or UEFI settings.
In the operating system, check if the USB device is hidden in the device manager, and if necessary, you can adjust the settings to show the hidden devices.
5. Fix operating system issues:
Make sure that the operating system is up to date and that all necessary updates have been installed.
Run the troubleshooting tools that come with your system, such as the Windows Hardware and Devices troubleshooter.
Boot up your computer in safe mode and try inserting a USB flash drive to see if it is recognized, to rule out possible software conflicts.
6. Data Recovery Preparation:
If you are worried about the data loss in the USB flash drive, you can consider using data recovery software to try to recover the data, or contact a professional data recovery service.
