Error Code 43

What is Error code 43?

Error code 43 is an error that usually occurs when a device fails or stops working and Windows stops it since it has reported problems.

How can you fix Error code 43?

Some of the solutions to this error include reinstalling the driver and enabling the "USB selective suspend setting."

Please see our in-depth walk-through solutions below.

• Reinstall the driver
• Enable USB selective suspend setting
• Use Atikmdag

1. Reinstall the driver

"Error code 43" may occur when a device or a device driver stops working, which sometimes is normal. Windows will only prompt you with a problem message but will rerun it back. For example, Windows will show a driver error, "NVIDIA driver stop working", after a while it will go back to normal. If the error only occurs, once in three months, for example, just restart your computer. But if the error persists and is messing with your daily operations, reinstalling the driver may fix the error.

NOTE: Try to reconnect the hardware first and test, before uninstalling the driver. If you are using a USB storage device connect it properly, Windows 7 and higher versions have a pre-installed universal driver for all USB storage devices.

1. Go to Control panel and select Uninstall a program.
2. Select the driver of that hardware where you are encountering the error and uninstall it.
   NOTE: Image below is for example purpose only.
3. Restart the PC and install the latest driver.
4. Then, restart and try your PC again.

2. Enable USB selective suspend setting

"Error code 43" may also occur in USB devices when your "USB selective suspend setting" has been disabled. You may want to enable it so the setting will not conflict with the USB driver.

1. Click Windows Start, type in Edit power plan and press Enter.
2. Click Change advanced power settings.
3. Expand USB Settings.
4. Enable USB selective suspend setting.

3. Use Atikmdag
