Easily Fix "USB Device Not Recognized" error in Windows

By Unknown Monday, April 8, 2013 0 comments
Are you getting a "USB device not recognized" error whenever you plug a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer in order to connect my mouse, keyboard, camera, phone and printer all at once!However, last weekend, my computer stopped recognizing my USB devices! The strange thing was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge the phone without a problem!
So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That did not work! Then I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That did not work!I read online that in order to solve this problem that should go into Device Manager and uninstall all devices under USB Controllers. Restart the computer, reinstall the USB drivers, but the problem still did not go away!You may also see in device manager that the device looks like an "Unknown Device".


So how did finally solve the problem? Well, apparently it's a super simple solution! No need to edit the registry, uninstall the drivers, or something like that.Just unplug your computer GRID. You are done! Note that this does not mean just turn off the computer because modern computers do not really turn off when you press the power button on the motherboard still gets power.Before I explain, the motherboard is where all the computer hardware is connected to, including the USB ports. Sometimes the motherboard needs to be "rebooted" also because something can go wrong, ie all your USB ports suddenly stop working. The small microprocessor on the motherboard reload the drivers and your USB ports should be back to recognizing all devices!So before you 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!
