Hi, 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!

usb device not recognized

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!


Have a nice day...

USB port gives new message "unknown device"


hello allan213

my name is ausi.

is it on all usb ports only one of them if it is in only one of them then the message you getting generaly means one of thw follwng.

1- if it is in only one of the ports then try it with a different device as well to see if it is the actual port or not.

2- the device you have plugged in needs to have drivers installed. normally should have been supplied with it.

3- the device you plugging in is faulty and the system can not access it.

4- the system usb ports are overloaded. (too many usb devices connected simultaneously)

good luck

My USB Ports of Sony Vaio VGN FW235 stopped working


first remove all the USB Devices connected to the Computer, go to Device Manager, uninstall all the USB Drivers and restart the Computer. after the restart, the Operating System should reinstall the USB Drivers automatically as the USB Drivers are Operating System generic.
If this does not work, go to Device Manager, right click on the USB Device having Yellow Exclamatory mark and click on Update Device/Driver and select search for the best driver in these location and in the location type C:\Windows\inf and click next.
This should resolve the issue.
If this does not work, you can try performing the System restore where the USB ports are working normally.

Unknown walkman


Downloading and installing driver from the website wont help much on this issue. It usually happens with the faulty usb port on the MP3 player or on the machine. Try connecting to another USB port on the machine. Also please check if the USB port on the machine is working fine

Unknown device


Hello,
Plug it through different USB ports, even a USB Hub, or on a different computer. Sometimes rebooting solves the problem. I suspect it is a USB problem, especially on laptops with a small number of USB ports.
I have given mine up as dead several times, but it always comes back up gain.
Hope it helps.

USB device unknown


Make sure you are connecting directly to the computer's USB port, not through a hub. Try disconnecting other USB devices before plugging in the camera. Check the manufacturer's website for updaded drivers: if all else fails, a reinstall of the camera's drivers may be in order.
