In Windows 2000, Device Manager only displays connected devices, even if you check View / Show hidden devices.
You can display ghosted devices, if you check View / Show hidden devices, by opening a CMD prompt and typing:
NOTE: You may need to replace %SystemRoot% with the actual drive and folder of your Windows 2000 install.
When you quit Device Manager, the %devmgr_show_nonpresent_devices% environment variable will become undefined, so you will need to start Device Manager using the above method to see ghosted devices again.
You can also set a global environment variable using Control Panel / System / Advanced / Environment Variables and entering devmgr_show_nonpresent_devices and 1 in the System Variables box, allowing you to start Device Manager normally.
NOTE: Ghosted devices are non-Plug and Play and devices which are not currently connected.
NOTE: You can also create a shortcut to a batch file, so you can have it both ways.
