USB Interfaces User’s Guide 1 - 19If you are working with a product that has recently been renamed, use the PID addresses for this product as well as the PIDaddresses for the former name of the product. If the product you are working with appears in the Device column of the tablebelow, not only must you reference its PIDs, but you must also reference the PIDs of the product identified in the respectiveAdditional Settings column.Registry EntriesWindows 9xThis 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 alreadyknows. 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 OSinstalls the correct class driver automatically. You can delete entries for a given device under Enum/USB, but it is notrecommended because it is possible for COMxx names to become locked. It is better to use the Device Manager to remove adevice from the registry.Device AdditionalSettingsIT5600 3800r3800r IT5600IT5800 3800i3800i IT5800IT4800 4800i4800i IT4800IT4200 42064206 IT4200IT2020 20202020 IT2020!
