After agonizing over this for two days, I unplugged the laptop and let the battery run down. Next morning, voila! The USB port is working again!

I just started having this issue today. I had several USB devices plugged into a desktop PC; keyboard, mouse, wireless-n adapter, etc. Today none of them will work and in fact, any other device (including just a standard USB mouse) will not work. “USB Device Not Recognized” is the message I receive.

I have uninstalled/re-installed, unplugged/re-plugged, updated, etc. I’m certain that the peripherals themselves are fine (as the chances of the all going out are almost 0%.) I read a mention of checking voltages but I can find no option to do so in the BIOS. I’m leaning towards a bad power supply but have no way to confirm this 100% without just buying a new one.

@jj – Yes, that is always an option, insert a PCI card with extra USB ports. Hope it works indeed!

Anthony, yes i also updated the driver of the mother board. model is msi pl45neo. now I have a new option. there is this internal usb that you will plug in on the pci slot. a lot cheaper than to buy a new mobo. hope it will work. I’ll let you know if it will work.

@jj – At least install the latest service packs and patches for your Windows version in case you haven’t, but if you already tried reinstalling your complete OS, chances are there is really something wrong with your USB ports. What is your Windows version?
And what is your computer model, or motherboard model?

hi. I got same error message too. mp3 players, mobilephones, flash drives, printers. they are not recognize on all of the 6 usb ports. so I tried, turning off and unplugging the pc from the poweroutlet, also shorted the bios, disable/enable the usb from the bios, editing the registry, uninstalling/installing the device as well as the drivers, changing hardrives installing new OS, turning off the power of usb root hub, updating drivers, change power supplies and still failed to fixed the problem. all of the usb device that I tried works on a a differnt computer.

please help. Im running out of options aside from changing mobos

@Shaikh – If the USB device does not work on any other computer as well, it is most likely that the device is broken. Have you tried different Windows versions (XP, Vista, Windows 7)? All the same result?

@Tessa – Windows updates are generally important, but I don’t install them automatically because they have caused problems in rare occasions as well. Second to that Microsoft likes to install a whole lot of stuff through the Update feature that I do not need, nor want on my system.
Regarding the USB device, simply try it on a different computer to see if it works there.

I experienced this before and I read that it is important to install Windows Updates. If it still won’t work, maybe the USB device is defective?

C Garner I had exactly the same problem. Then I remembered that a few days before I had been copying photos from my cruzer micro 8GB memory stick onto my computer and when I had finished I had pulled the stick out of the computer rather than clicking on the ‘Safely Remove Hardware’ icon. I put the stick back in and this time clicked on this and highlighed my cruzer and waited until I got the message saying it was safe to remove hardware. This fixed the problem
