How to fix 'This device is not configured correctly. (Code 1)'

The device manager displays exclamation marks usually caused by hardware connection problems or driver abnormalities. The solutions are as follows: 1. Check the device connection and power supply, ensure that it is plugged and unplugged and uses live HUB or replace the interface; 2. Update or roll back the driver, and obtain the latest driver through the device manager or official website; 3. Clean up the residual information of the old device, uninstall the hidden device and re-identify it; 4. Carefully modify the registry, delete the exception after backup; if it still cannot be solved, try reinstalling the system.

This error message usually appears in Windows Device Manager, indicating that the system cannot correctly identify a hardware device. Although the prompt seems serious, it is not a big problem in most cases and can be solved through a few simple steps.

Check the device connection and power supply

First, confirm whether the external device is plugged in well, especially USB, graphics card expansion or other PCIe devices. Sometimes it is just a false alarm caused by poor contact or insufficient power supply.

• If it is an external device, try changing to a USB port or using a powered HUB
• For internal hardware (such as sound cards, network cards, etc.), plug and unplug and unplug after shutdown to ensure good contact
• Some devices require additional power cables to check if the motherboard is connected

If the device itself shows signs of damage, such as capacitor bulge or burn marks, it is recommended to replace the device before testing.

Update or rollback the driver

This is the most common solution. Windows sometimes experiences compatibility issues after updating the driver, resulting in device status abnormality.

1. Open Device Manager and find the device with a yellow exclamation mark
2. Right-click to select "Update Driver" → Automatically search for updates
3. If you have recently updated the driver, you can try "rollback the driver"

You can also manually go to the device official website to download the latest driver installation. For example, Intel, Realtek, NVIDIA and other manufacturers all provide detailed driver support pages.

Clean up residual information of old equipment

Sometimes, after uninstalling the device, the system still retains the old configuration information, which may lead to conflicts.

• Click "View" in Device Manager → "Show Hidden Devices"
• Find the relevant device entry, right-click and select "Uninstall Device"
• Check "Delete driver software for this device" before confirming uninstallation
• Then plug in the device or restart the computer to re-identify the system

Modify the registry (operate with caution)

If you are sure that the hardware is fine and the driver is up to date, you can also try to adjust the device configuration parameters in the registry. This step requires caution, and it is recommended to back up the registry in advance.

The path is roughly:计算机\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\

After finding the corresponding device ID, check whether there are any exceptions, or try to delete and let the system regenerate.

Basically these are the methods. Most of the situation can be solved through the first two steps, and the final registry change operation is not recommended for novices to try it easily. If you encounter repeated errors, you can also consider reinstalling the system and try it.
