USB not recognized issues with Windows 7

How many of you are having this problem?  Lots I am sure...it is quite frustrating.....well, here's a fix without having to do system restore (which does not work), or editing the registry (which can be disastrous-if you don't know what you are doing!)...

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!

In other words, this process "refreshes" the system board and gives it a new boost....
If it does not work there may be other issues with your computer....    :(
