Remove and reinstall all USB controllers

This post describes how to remove or reinstall Universal Bus Controller (USB) devices in windows XP.

If you have a problem with a USB device, try these methods first:
1. Unplug and then plug in the device.
2. If the computer prompts you for a device driver, read the information that was included with the device, or visit the manufacturer's Web site to see whether a driver is available.
3. Run Windows Update to obtain the latest fixes for Windows XP. When this is complete, plug in the device to see whether it is installed correctly.

Because USB devices are Plug and Play devices, there is little that you can do to control or configure them. However, you can trace most USB problems to one of the following conditions:
• Malfunctioning or incorrectly-configured hardware
• Malfunctioning, incorrectly-configured, or missing device driver
• Mismatched cabling
• Out-of-date firmware or basic input/output system (BIOS)
• Incorrectly-configured root hub
You can use the following troubleshooting tips to check for each of these conditions to help you resolve USB device issues.

To remove and reinstall all USB controllers, follow these steps:
1. Click Start, click Run, type sysdm.cpl in the Open box, and then click OK.
2. Click the Hardware tab.
3. Click the Device Manager button.
4. Expand Universal Serial Bus controllers.
5. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
6. Restart the computer, and then reinstall the USB controllers.
7. Plug in the removable USB storage device, and then test to make sure that the issue is resolved.
