Are you getting a “USB device not recognized”
error whenever you plug in a USB mouse, keyboard, or other USB device? I
love USB and have 5 ports on my computer so that I can connect my
mouse, keyboard, camera, phone, and printer to it all at once!
However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!
However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!
So I started with the 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!
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!
