This section contains information about modifying your computer's registry. Before you modify the registry,
be sure to back it up first, and make sure you understand how to restore the registry if a problem occurs.
Entries for all USB devices are under HKEY_LOCAL_MACHINE. Inside this key, look for Enum/USB.
Every time you plug in a USB device, the OS updates the Enum/USB entries in order to keep track of all the devices it already
knows. If a device is not yet listed, the OS asks you for a driver. Some devices are known by the device class (HID) and the OS
installs the correct class driver automatically. You can delete entries for a given device under Enum/USB, but it is not
recommended because it is possible for COMxx names to become locked. It is better to use the Device Manager to remove a
device from the registry.
