Start with the normal fixing methods, including
uninstalling the drivers for your devices and reinstalling them. if That
didn't work! Next try System Restore thinking that maybe you have installed something and it caused a conflict with the USB system
drivers. That didn't work!
go to Device Manager and uninstall all of the devices under USB
Controllers. Restart the computer, reinstall the USB drivers,
You may also see in Device Manager that the device shows
up as an "Unknown Devic
last fix for 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.
