Right click the one thats the problem (or all of them if you dont know which), select Uninstall
Reboot your machine and windows will autodetect the USBs and reinstall their drivers.

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 wont recognize anything I plug in

Are you using XP? If so:
Here is what you can do to refresh the USB ports:
1. Right click MY COMPUTER
3. Select HARDWARE
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB device.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

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.

Thinkpad T20 won't recognize usb port

You can get a PCMCIA adapter with 4 USB v.2.0 slots on eBay. It requires power from the USB port on the laptop, but the pigtail connector is included. Works like a charm! Comes from China just like everything else in this country.

Usb ports

  • 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.

    Usb ports

    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.
