This is the error i received recently when i was trying to connect my phone to my laptop. The time i realize other people might have facing the same problem. As we all love USB ports and want to connect our keyboard, mouse, phones to computer all at once through USB ports and this kind of error was really annoying.
so i tried to figure out a solution for this error by starting with normal fixing methods including uninstalling the drivers for my devices and reinstalling them. That didn’t work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn’t work!
How To Fix This Problem:
I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!
You may also see in Device Manager that the device shows up as an “Unknown Device”.
So how did I finally fix the problem? Well, apparently it’s a super simple solution! No need to edit the registry uninstall drivers, or anything of that sort.
Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that’s it! Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.
First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.
Hope this helps someone fix that pesky “USB device not recognized” Windows error!
