Top 9 Methods to Fix the “USB (Set Address Failed)” Error

After connecting a removable drive to your PC, does your Device Manager display the “Unknown USB Device (Set Address Failed)” error, be it on Windows 10 or Windows 11? Don’t worry—you can quickly fix this problem with the tried-and-tested methods below.

These methods can also eliminate the “USB (Device Descriptor Request Failed)” error. It’s similar to a failed set address request, except it prevents your computer from identifying your USB’s configuration, product ID, vendor ID, and class information.

The same goes for the “USB (Port Reset Failed)” error, indicating your USB port can’t recognize the device. The fixes below can resolve it, but let’s see what causes the “USB (Set Address Failed)” error before exploring them.

“Unknown USB Device (Set Address Failed)” Explained

Once you plug a USB drive into your PC (the USB host), the computer assigns it an address—a unique identifier enabling communication between the two devices.

That dynamic, seven-bit address is part of the token packet your PC sends to the USB drive to differentiate it from other devices and initiate a USB transaction. That transaction can’t start if the host doesn’t specify the address. That’s when you get the “Unknown USB Device (Set Address Failed)” code 43 error.

The error code 43 means your computer’s graphics device driver has detected a hardware or driver software issue, notifying Windows that the connected USB device doesn’t work correctly. Fortunately, you can fix the problem, but why does it happen in the first place? Let’s find out.

Common Causes of “USB (Set Address Failed)”

The primary culprits of the “USB (Set Address Failed)” error include the following:

• An outdated USB driver (or corrupted due to a failed software update)
• A damaged or faulty USB port
• A malfunctioning or failing laptop charger
• Misconfigured USB driver settings
• A USB device that has been tampered or corrupted with malware.

Regardless of the problem, you can eliminate it with the proven methods below.

How to Fix the “Unknown USB Device (Set Address Failed)” Problem

You can try the following fixes for “Unknown USB Device (Set Address Failed)” on Windows 11, 10, and older OS versions.

Disconnect Your Charger

This method works if you use a laptop. Namely, a malfunctioning charger can cause the error code 43 when connecting a USB device to a laptop. Although rare, it can happen on Windows 10 computers.

The fix couldn’t be more straightforward:

1. Disconnect the USB device (use the “Safely remove hardware” option).
2. Unplug the charger from your laptop.
3. Reconnect the USB drive.

If that doesn’t resolve the problem, the methods below should. However, if you no longer see the error code 43, you might need to replace your charger.

Adjust Power Options

This method also concerns laptops. Your laptop might suspend connected USB devices (among other functions) to preserve power once its battery drops to 20%. That can cause the “USB (Set Address Failed)” error.

The same goes for connecting a USB drive while your laptop runs on AC power but hasn’t recharged beyond 20%.

Here’s how to adjust your power plan settings to fix the problem:

1. Go to Control Panel > Hardware and Sound > Power Options and click Change plan settings under your selected power plan.

1. Click Change advanced power settings.

1. Expand USB settings and switch both options under the USB selective suspend setting to Disabled. Click Apply > OK.

Restarting your PC will apply the changes and should resolve the issue. If it persists, try the following method.

Turn off Fast Startup

The Fast Startup feature on Windows 8, 10, and 11 combines the shutdown and hibernation modes to enable a faster system boot. However, that creates a hibernation system file after logging you out and closing all programs.

Once your PC boots, it doesn’t reload the system state, the Windows kernel, and all the drivers but loads the hibernation file’s image. That can be problematic because booting your PC may not apply updates and other system changes, which is what you need when fixing USB device problems.

Although restarting your PC will bypass Fast Startup, here’s how to turn it off so it doesn’t cause issues:

1. Go to Control Panel > Hardware and Sound > Power Options and click Choose what the power buttons do.

1. Untick the Turn on fast startup (recommended) checkbox under Shutdown settings and click Save changes. (You’ll see the “Change settings that are currently unavailable” option if the Shutdown settings are grayed out, so click it to enable modifications).

If the problem doesn’t resolve after restarting your PC, try other fixes to eliminate the error code 43.

Update USB Drivers

Outdated or corrupted USB drivers might cause a failed USB set address request. Here’s how to update yours on any Windows version:

1. Connect your USB device to your PC.
2. Launch Device Manager from the Start menu.
3. Expand Universal Serial Bus controllers, right-click your problematic USB drive, and click Update driver.

1. Select the Search automatically for updated driver software option and wait for your PC to find and install a suitable one.

You’ll see a success message if the method works. Otherwise, try the following fix.

Uninstall and Reinstall the Device

Uninstalling and reinstalling your USB device might eliminate the error because your computer will install the latest compatible software for the USB drive. Here’s what to do:

1. Follow Steps 1–3 from the previous method, but click Uninstall device instead of Update driver.

1. Follow the on-screen instructions and restart your PC.

Your computer will automatically reinstall the USB device driver, and the yellow triangle with an exclamation mark next to it should be gone.

You can check if the method worked by right-clicking your USB device, selecting Properties, and reading the status message in the General tab—it should say, “This device is working properly.” Otherwise, apply the following method.

Scan for Hardware Changes

Scanning your computer for hardware changes will reinstall your USB device driver after uninstalling it. It’s an excellent method for all hardware modifications. Here’s what to do:

1. Relaunch Device Manager after restarting your PC.
2. Go to Action > Scan for hardware changes.

Your USB device driver will reinstall, but here’s another proven fix if this one doesn’t bear fruit.

Use the USB Troubleshooter

Windows USB Troubleshooter is a tool from Microsoft that might help resolve the “Unknown USB Device (Set Address Failed)” problem on Windows 10 and older versions. Here’s how to use it:

1. Connect your USB device to your PC.
2. Download Windows USB Troubleshooter (Microsoft archived this direct download link, but it still works on Windows 10 and older).
3. Install and run the tool as administrator. Click Next to initiate scanning.

1. The software will run diagnostics to detect problems; it might take several minutes.

1. The tool will list all problematic USB devices and prompt you to select the one you wish to repair. Click Next and wait for it to fix the problem.

If you can’t download Windows USB Troubleshooter, or it doesn’t resolve the issue, here’s how to use its built-in counterpart.

Troubleshoot Hardware and Devices

Windows has built-in troubleshooters for various devices, hardware, and programs. You can troubleshoot network adapters, USB and Bluetooth devices, printers, playing and recording audio, video playback, and other software and hardware.

Here’s how to use a troubleshooter to fix “Unknown USB Device (Set Address Failed)” on Windows 10:

1. Connect your USB device to your PC.
2. Go to Settings > Update & Security > Troubleshoot > Hardware and Devices.

Whether you use Windows 10 or 11, your chosen troubleshooter will detect the issue and recommend a solution, so select it and wait for it to finish.

Turn Off BitLocker Encryption

Although rarely the culprit for the “USB (Set Address Failed)” error, BitLocker might interfere with your encrypted USB device’s set address request. Here’s how to turn off the encryption to see if it resolves the problem:

1. Connect your BitLocker-encrypted USB device to your computer.
2. Unlock it with your BitLocker To Go password.
3. Launch File Explorer, select This PC, right-click the USB drive, and click Manage BitLocker.

1. Expand the section with your removable drive, click Turn off BitLocker, and confirm the choice.

Restart your PC once it removes BitLocker encryption from your USB drive (which might take a while).
