How to delete unnecessary USB drive signature from Windows XP and Vista?

When you connecting a new USB device to your computer, Windows will automatically installs its driver signature on your system (if it is not already installed). However, how can you delete a USB drive or a particular USB device’s hardware signature that are not required anymore from Windows XP or Vista?

In order to show and delete installed USB devices that are not currently connected to the computer, you can use either a command prompt or a little tool USBDeview from Nirsoft.

USBDeview is a small and very easy to use utility that lists all USB devices that currently connected to your computer, as well as all USB devices that you previously used.

It will give you information such as Device name/description, device type, serial number (for mass storage devices), the date/time that device was added, etc. You can uninstall USB devices that you previously used by right clicking it, or disconnect USB devices that are currently connected to your computer.

You can also use a command line utility DevCon from Microsoft (Windows XP). This utility acts as an alternative to Device Manager and you can enable, disable, restart, update, remove, and query individual devices or groups of devices. DevCon also provides information that is relevant to the driver developer and is not available in Device Manager.
