1. Check whether the U disk is damaged

First, we need to confirm whether the U disk itself is damaged. Insert the USB flash drive into another computer to see if the data can be recognized and read normally. If it cannot be recognized on other computers, it is likely that there is a problem with the USB drive itself, such as physical damage or file system error. In this case, you may need to replace the USB flash drive with a new one.

If the USB flash drive can work normally on other computers, it means that the problem lies with the current computer. Next, we continue to investigate.

2. Check the USB interface

Sometimes, the computer cannot recognize the U disk because there is a problem with the USB interface. You can try inserting the USB flash drive into another USB port on your computer to see if it can be recognized. If the USB flash drive can work normally after changing the interface, it means that the original USB interface may be faulty and needs further inspection and repair.

In addition, make sure the USB port is not blocked by dust or foreign objects. You can use tools such as compressed air or cotton swabs to clean the USB interface to ensure good contact.

3. Update or reinstall the USB driver

If there is no problem with the USB interface, it may be that the USB driver is abnormal. You can try updating or reinstalling the USB driver to resolve the issue.

First, right-click the "Start" menu and select "Device Manager". Find "Universal Serial Bus Controller" in the Device Manager, expand it and find the device with the word "USB", right-click and select "Update Driver". You can choose to automatically search for updated drivers, or manually browse for downloaded driver files to install.

If updating the driver does not work, you can try uninstalling the USB driver, then restart the computer and let the system automatically reinstall the driver. Right-click the USB device in the Device Manager, select "Uninstall Device", check "Delete the driver software for this device" and confirm the uninstallation. Then restart the computer and the system will automatically install the default driver.

4. Check and repair the registry

If none of the above methods work, the problem may lie in the system registry. You can use third-party tools such as USB Device Tree Viewer to check and repair USB-related entries in the registry.

Be sure to back up the registry before use to avoid modification errors that may cause system problems. Then open the USB Device Tree Viewer, click "View" on the menu bar, and check "Show Disconnected Devices". Find the device representing the USB flash drive, right-click and select "Uninstall Selected Devices". Make sure to check "Delete driver software for these devices" below. After the operation is completed, restart the computer and the system will automatically install the USB driver.
