Understanding the root cause of the problem is the first step in effectively resolving it. Let’s examine the troubleshooting steps to address each of these potential issues.

Troubleshooting Steps for USB Device Not Recognized Error Code 43

Updating USB Drivers in Windows 10

One of the most common causes of the “USB Device Not Recognized” error is outdated or corrupted USB drivers. To address this, follow these steps:

1. Right-click on the Start button and select “Device Manager.”
2. Expand the “Universal Serial Bus Controllers” section.
3. Right-click on the USB device that’s not being recognized and select “Update driver.”
4. Choose “Search automatically for updated driver software” and let Windows 10 search for and install the latest driver.
5. If Windows cannot find an updated driver, you can download the newest driver from the manufacturer’s website and install it manually.

Checking USB Ports and Connections

Next, let’s ensure that the physical connection between your USB device and the computer is working correctly:

1. Try plugging the USB device into a different USB port on your computer.
2. Check the USB cable for any signs of damage, such as fraying or loose connections.
3. If you have another USB device, try plugging it into the same port to see if it’s recognized. This can help you identify if the issue is with the port or the device itself.
4. If the USB port is automatic, you can use a USB hub or a different computer to test the device.

Restarting the Computer and USB Device

A simple restart can sometimes resolve the “USB Device Not Recognized” error. Follow these steps:

1. Shut down your Windows 10 computer.
2. Unplug the USB device from your computer.
3. Wait for 30 seconds, then plug the USB device back in.
4. Turn on your computer and see if the USB device is now recognized.

Resolving Power Supply Issues

Insufficient power supply to the USB device can also cause the “USB Device Not Recognized” error. Here’s how to address this:

1. If an external power supply powers the USB device, ensure it’s properly connected and functioning.
2. Try plugging the USB device directly into a USB port on your computer instead of using a USB hub or extension cable.
3. If the device is a high-power USB device, such as an external hard drive, you may need to use a powered USB hub to provide enough power.

Disabling the USB Selective Suspend Setting

The USB Selective Suspend setting in Windows 10 can sometimes cause USB devices to be unrecognized. Follow these steps to turn off this setting:

1. Open the Control Panel and navigate to “Power Options.”
2. Click on “Change plan settings” for the currently selected power plan.
3. Click on “Change advanced power settings.”
4. Expand the “USB settings” option and set “USB selective suspend setting” to “Disabled.”
5. Click “OK” to save the changes.

Updating Windows 10

If the above steps haven’t resolved the issue, a problem with your Windows 10 operating system may be causing the “USB Device Not Recognized” error. Try updating your Windows 10 to the latest version:

1. Open the Start menu and search for “Windows Update settings.”
2. Click on “Check for updates” and let Windows 10 download and install any available updates.
