You'll want to verify your computer recognizes your usb ports.
In device manager, look to see that you don't have anything with an exclamation mark, question mark, or red X on it. Make sure you have the usb ports listed under Universal Serial Bus controllers. If nothing shows, your usb ports may be dead. Depends on the age of your computer and what might have happened to them.

Device manager- right-click My Computer and go to properties, then select the hardware tab.

One of my usb ports won't work properly. If you plug something to it for longer than half an hour the usb port stops recognizing the device you plugged. I have an hp dv7 4190us laptop.


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.

Usb ports not working. power is on but computer doesnt detect anything plugged in. win xp


Hi..

Did you try the other port of your motherboard. Do not use the front USB socket of your computer, you need to plug i directly to your motherboard ports. If the same things happen. you need troubleshooting.

I have a WD passport 320gb, at first it worked one of my usb. then all of sudden, it stop recognizing my WD Passport with one usd port, so i plug it in another usb then it works. and after a couple of days...


Are you using an external power supply for the disk? If not, you might be overloading the USB port. It should not happen, but USB ports are limited in the amount of power they can output. Especially laptops might face such problems.

Do other USB devices still work on those USB ports? If so then the port is at least not broken.
Sometimes you can uninstall and reinstall the USB hubs and controller devices in the Device Manager to fix USB problems.

I added a 512mb stick to my ibm t30 think pad and one port is bad


You can plug a USB hub into the working USB port on the computer. The USB hub can have several ports so you can plug in several USB devices.
I suggest you get a powered USB hub because if all the devices that you plug into this hub exceeds 500mA then your computer's USB port will stop working because it could not supply enough current.
You will not need to plug in the power adapter into the hub if the device/s do not overload the computer's USB port.

To uninstall a device
  1. Open Device Manager.
  2. Double-click the type of device that you want to uninstall.
  3. Right-click the specific device you want, and then click Uninstall. You can also double-click the device, and then on the Driver tab, click Uninstall.
  4. In the Confirm Device Removal page, select Delete the driver software for this device if you also want to remove the device driver package from the driver store. .
    The Delete the driver software for this device option removes the package from the driver store. It does not remove the currently installed driver for any other operational devices that use the same driver. If you remove the driver from the store, and the device is connected to the computer again, Windows must search for a copy of the driver package in the standard search locations, including possibly prompting the user for media. This option is the equivalent of running the command: pnputil -d -f <package.inf>. For more information, see Remove a Driver Package from the Driver Store.
  5. Click OK to complete the uninstall process.
  6. When the uninstall process is complete, unplug the device from the computer.
    If you are prompted to restart the computer, the removal is not completed and the device might continue to function until the computer is restarted.
Reinstall a Plug and Play device Reinstall a device only if it is working improperly or it has stopped working altogether. Before you reinstall a device, try to restart your computer and check the device to determine whether it is functioning properly. If it is not, try reinstalling the device.
To reinstall a Plug and Play device
  1. Open Device Manager.
  2. Follow the instructions in the preceding procedure to uninstall the device.
  3. If you are prompted to restart the computer, follow these steps:
    • Plug in the device and then restart the computer. The device will be detected and reinstalled after Windows restarts.
    • Follow any instructions on-screen to complete installation.
  4. If you are not prompted to restart the computer, follow these steps:
    • In Device Manager, in the Action menu, click Scan for hardware changes.
    • Follow the instructions on the screen.

  • The driver for the device is faulty. When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver. If the computer prompts you for a device driver, check the information that came with the device or go to the manufacturer's website to see if a driver is available.
  • The USB port might be defective. If the USB device is connected to a defective port, the device will not work. Try plugging the device into a different port. If all the USB ports are being used, unplug a device that you know works, and then plug the problem device into the port that device was using.
    If the device is plugged into a secondary USB hub with other USB devices, unplug the device from the hub, and then plug the device directly into a port on your computer.
  • Other USB devices might be drawing too much power from the hub. The device you are trying to use might require all the available power or bandwidth that your computer can provide. If other USB devices are connected to the computer and are drawing power from it, the first device might not work. If any other devices are drawing power from the hub, try disconnecting them, and then see if your device works. If this solves the problem, you might want to obtain a USB hub with its own power supply so that you have adequate power for all devices.

    If you've updated your software and checked the drivers but the issue still persists, try the following things:
    • Unplug the USB device and then plug it back in. Make sure that the connection is snug and installed in the proper direction. Note that USB plugs fit one way only—if you try to plug them in upside-down, it will not insert.
    If this does not solve your issue-
    • Unplug all USB devices from the computer. Then start plugging in USB devices one at a time, testing each one to make sure they all work before adding the next. Sometimes two devices will conflict and will work together.
    If this does not solve your issue-
    • Is this a new device that never worked, or is it a device that you've had for a while that suddenly stopped working? If it used to work, think about what changed just before the device stopped working. Did you recently add another new device? Install a new program? Try reverting the computer to the way it was before the device stopped working. If it works again, there is an incompatibility with the device and whatever you added.
    If this does not solve your issue-
    • Unplug all but suspected USB devices. Open System Devices menu-
      • Windows: Right click “My Computer” > Properties > Hardware > Device Manager > USB Serial Bus Controllers
      Under the USB information, you should see the USB devices connected to your system. (Disregard any Host controllers) The name may not be identical to your device (it may say “USB Mass storage device”), but it should have the right number of devices listed.
    If this does not solve your issue-
    • If you have the device plugged into a USB hub or into your keyboard, plug it directly into one of the USB ports on the computer. If it works there, the issue is with the device to which it had been previously connected. The device may need more power than the port provides
    • Try a different computer!
