If you receive Device Manager Error Code, Windows has stopped this device because it has reported problems (Code 43) on your Windows 11/10, using Intel, Radeon or AMD Graphics Cards (GPU), then see this post will help you fix the issue. You may have received this for an Intel or AMD Graphics Cards (GPU) as well.
What is Code 43 problem in USB?
We generally connect various peripheral devices to our Windows computer. These devices could be USB drives, printers, external mouse, keyboards, etc. Many times, you might have faced a problem in installing and using some devices. Recently we came across such an issue with a USB drive. In this case, whenever we tried to plug in the USB drive, Windows couldn’t recognize it, and thus we couldn’t use this drive for any operation.
As you can see in the above screenshot, there is an exclamation mark against the Unknown Device. Thus we further investigated this device and opened its Properties by double-clicking Unknown Device. The Device Status here says:
Windows has stopped this device because it has reported problems (Code 43)
You may face this error code with any of the devices you plug into your system. Speaking technically about the situation, the device driver here notifies Windows that the device has failed. This could also happen if the device hardware fails or if the device driver itself fails. In either case, the result is that you’re not able to use the device at all.
A few things you could try before you proceed with troubleshooting is:
- Restart the computer and see if the problem goes away
- Disconnect all other USB devices
- Unplug & plug the device back
- Run the Hardware Troubleshooter
- Update your device drivers
- Reinstall the device driver
- Roll back the device driver.
Let us take a look at them in detail:
1] Restart the computer
Restart the computer and see if the problem goes away
2] Disconnect all other USB devices
Disconnect all other USB devices and see if that helps,
3] Unplug & plug the device back
Unplug all your external devices and then plug the device back and see if that works.
4] Run the Hardware Troubleshooter
Run the Hardware Troubleshooter as well as the USB Troubleshooter. That has been known to help many.
5] Reinstall the device driver
If it doesn’t help, try to uninstall and reinstall the device and see if it helps:
Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.
In the Device Manager window, locate the malfunctioned device and right-click on it, select Uninstall.
After uninstalling Unknown Device in the previous step, right-click your computer name and select Scan for hardware changes.
In this way, finally, the malfunctioned device gets recognized by Windows and you can double click to view its Properties where you found the Device Status that This device is working properly.
6] Update the device driver
Windows 10 Updates now offer drivers by the OEMs when it passes through its compatibility test. It is possible that the latest version of Windows 10 and the driver are not compatible with each other. You can either manually update your device drivers by downloading from the OEMs website or check with Windows Update.
- Press WIN + X + M or right-click the Start button, and then select Device Manager.
- Expand the list of devices, and look for a device that has a yellow exclamation next to it. This signifies that the device has an issue.
- Right-click the device and select Properties.
- Select Driver, and then select Update Driver.
- Select Search automatically for updated driver software.
This will force Windows Update service to look for the latest driver. If a driver update is available, it will install automatically. Select Close when it finishes installing. You may have to restart your Windows 11/10 PC in some cases.

7] Roll back the device driver
While the latest drivers are rolled out to make sure to keep issues at bay with every Windows 10 Upgrade, sometimes it doesn’t work. If you have an update that was recently installed or you had manually update the driver software using the OEM Software, the only way out is to roll back to the previous version of the driver which was working.
- Go to Device Manager.
- Find the device which was causing the problem. It will be marked with a yellow exclamation point next to it.
- Then tap and hold or right-click the device and select Properties.
- Select Driver, and then select Roll Back Driver.
If this doesn’t work, we suggest you use System Restore feature to get back to the state where it was working fine. Windows usually creates a restore point whenever it installs something.

Let us know if this helped!
Yeah I knew this already. I don’t know though what kind of device it supposedly mean as Unknown..
But if I choose to “Scan for hardware changes”, it recognize my fake “virtual” monitor and I don’t want that!
This is the phenomenon I wonder if you can explain and help me with:
I have 1 monitor for my pc wich is an BenQ M2700HD and if I for example log out and back in it starts using this “general monitor” or whatever it’s called in english in the dev manager.. How is it that it rather wanna use my (nonexistent) monitor when I already got 1 REAL monitor connected?
I tried many stuff like setting or deselecting som checkboxes in policymanager and regedit but none prevents Windows from initializing this virtual monitor..
Any ideas?
I also had similar issues with devices. I solve most by deleting all hidden devices which are not connected. :-)

hi there! i’ve tried this but still the device was not successfully installed..what should i do? can anyone help me pls?
i have this same problem
If you are running Windows 8.1 and have this problem there is a fix at
http://support.microsoft.com/en-us/kb/3013769#fixed_issues the one referenced here is not for 8.1. The registry key changes are supposed to be part of the fix for Windows 8.1 but the actual “hotfix files are not. In fact, if you run it it will tell you that the hot fix is not compatible and won’t let you run it. Its odd because I found it looking at my “windows update settings,” when I checked for the optional updates that are not auto installed, but the yesterday I checked it and that one wasn’t there. Maybe it was good timing…
didnt work
nice one… Not working…
Same, it didn’t do anything for my cheap a$$ bluetooth dongle, got the same error code after scanning.
thank you…worked just great !
This took care of my Acer 22″ touch screen monitor not working suddenly in Windows 10 Pro 64-bit…thank you!!
Wow- from a jet engine to quite as normal. Thanks a ton!
This does not work. I was confused at step 3. But got the step on Scan for hardware changes. After this, it says ‘restart compute’. I am not sure if I need to disconnect my iPhone. I restarted the computer with iPhone connected. But it did not connect the iPhone. I reconnected the iPhone. It gave the same notice saying ‘unknown device’. So now what is the solution? I need to connect my iPhone to download pictures on it.
this is FALSE!!! DOES NOT WORK!!! it just IMMEDIATELY goes RIGHT BACK INTO “unknown device” on a BRAND NEW EXTERNAL HARD DRIVE
THANK YOU SO MUCH ADMIN
Brand new dvd writer installed and worked yesterday doesn’t get recognised today
