Windows has stopped this device because it has reported problems (Code 43)

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 for 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 above screenshot, there is an exclamation mark against the Unknown Device. Thus we further investigated about 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)

Error-Code-43-2

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 troubleshooting is – Restart the computer and see if the problem goes away, disconnect all other USB devices, unplug & plug the device back, update your device drivers, run the USB Troubleshooter as well as the Hardware Troubleshooter.

If it doesn’t help, try to uninstall and reinstall the device and see if it helps:

1. Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.
