Error code 43 indicates that Windows disabled a USB device because it reported an error. This is usually caused by a problem with the device driver. Here are some common solutions:

Reseat the device: First, try to unplug the USB device from the computer, wait a few seconds and then plug it in again. Sometimes this can solve the temporary connection problem.

Update device drivers: Go to computer manufacturer official website or equipment manufacturer official website to download and install the latest device drivers. Make sure to select a driver that is compatible with your operating system and device model.

Uninstall and reinstall the device driver: In Windows, press Win+X and select Device Manager. In Device Manager, locate the problematic USB device, right-click it, and select Uninstall Device. Then restart the computer. Windows will automatically install the default driver. If the driver is not installed correctly, you can download and install the official driver manually.

Update Operating System: Make sure that your Windows operating system has been updated to the latest version. Windows updates may contain patches to fix problems related to USB devices.

Try to test the device on another computer: if possible, connect the USB device to another computer to see if the same problem will occur. If you encounter problems on other computers, it may be that the device itself is faulty.

Check the USB port and cable: Make sure that the USB port is not damaged or loose, and try to connect devices with different USB cables to eliminate the possibility of port or cable failure.
