COMMENTS:
If the device does not have a yellow bang (!) or red "X" on its icon, then the device is functioning properly but is misidentified by the OS. This is a limitation of the OS and is common when an older Operating System does not properly recognize newer technology and there are no Service Packs from the OS manufacturer to provide more current files. To clean up the Device Manager and keep it from displaying the Unknown Device, "masking" the device through the registry is required.

The following procedure involves editing the system Registry files. Using the Registry Editor incorrectly can cause serious problems which may cause the loss of data, and may require you to reinstall Windows. Neither Toshiba nor Microsoft will guarantee that problems resulting from the incorrect use of Registry Editor can be solved. For information related to editing and restoring the registry, view the online Help topic in Registry Editor (Regedit.exe).

Important: You should always make a backup copy of the registry files before you edit the registry.

Use the Registry Editor at your own risk!
