More Information and Manual Resolution
Firstly, restart your computer; this can often solve the problem in itself.
If this fails then it’s possible that a small change that you’ve inadvertently made to Device Manager has caused the fault. So undo recent changes.
The next thing to try is to remove the newly installed device and then reinstall it.
If this doesn’t work then try downloading the most recent driver from the website of the device’s manufacturer.
If this doesn’t work then the next option worth attempting is to use system restore function. This will reset your machine to a time before the error caused your machine to malfunction. You can then re-install any devices or programmes that have been removed by this virtual step back in time. System restore can be accessed through the Start menu, by simply typing “System Restore” into the search box.
If the system restore utility will not run correctly then you can attempt to activate safe mode. To activate Safe Mode, hold F8 when your computer is initially booting up. Once you’ve reached the desktop in Safe Mode, type ‘System’ into the Start search box and press Enter once ‘System Restore’ is highlighted. You should then be able to run the system restore utility.
If none of these steps does any good at all then you have to entertain the probability that there is a hardware error. You would be advised to contact the manufacturer. It’s also possible that the device is not compatible with the version of Windows that you are using, but the manufacturer will be able to advise on this matter.
