USB devices are one of the commonly used devices every day – from plugging mobile devices for charging using pen drives, you are making use of USB drives. However, there are times when you might encounter an error message saying, “Unknown USB Device” as you plug your USB device on your Windows 10 computer. So if you encounter this kind of error message followed by either of the following explanations, read on as this post will give you a couple of suggestions you can check out to resolve the issue.
You can fix this error using several ways. You can try changing the Power Options, update or roll back the USB drivers, turn off Fast Startup, or run the USB troubleshooter. Follow the options given below for more details.
Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.
takeown /f FileNameAndPathNote: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:
icacls FileNameAndPath /GRANT ADMINISTRATORS:FNote: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:
copy NewFileLocation FileNameAndPathNote: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”
“Windows cannot install required files. Network problems may be preventing Windows from accessing the file. Make sure the computer is connected to the network and restart the installation. Error code: 0x80070006.”As stated in the error message, this kind of error in Windows Setup is due to an unstable or unreliable network connection. Such problems can also be triggered by network hardware which includes the network adapters and the network routers. To fix this error, you need to check your internet connection and router or run the built-in network troubleshooter. You could also try using a different USB port or recreate a bootable USB drive as well as get a new Windows image file.
