USB code 43 is a device manager error code that means that Windows has stopped this device because it has reported problems. There can be many reasons for this error, but most often it is because the device is not compatible with the version of Windows that you are using, or because the drivers for the device are not installed correctly.

Users typically search for a solution by asking about:

1. Check if the USB device is properly plugged in

  1. If the USB device is not plugged in properly, it may not work properly. Try plugging it in again.
  2. If the USB device still does not work, it may be defective and should be replaced.

2. Try a different USB port

Start by checking to see if the device is properly seated in the USB port. If it is not seated properly, you may need to wiggle it around until it is. If the device is properly seated, try connecting the device to another USB port on your computer. If the device still does not work, you may need to try a different USB port on your computer.

3. Try a different USB cable

  1. Remove any devices plugged into the USB port.
  2. Plug the USB cable into the back of your computer and into the USB port on the device.
  3. Turn on the device and the computer.
  4. If the device shows up as a new device in Windows, make sure the driver is installed. For Mac, use the "Disk Utility" app.
  5. If the device does not show up as a new device, try to connect it using a different USB cable.

If the answers above didn't work then you should also try:

  1. Update the drivers for the USB device.
  2. Uninstall and reinstall the drivers for the USB device.
  3. Disable and then enable the USB device.
  4. Restart the computer.
