Stopping a USB Device in Windows 98

How do you properly stop a USB device in Windows 98 ?

In Windows 2000, you click on the icon on the tray in the main Toolbar. Then
click Stop device. There is no such functionality in Windows 98. Can I just
pull the plug out ?

The reason I ask is I am having some device removal bugs in my WDM Driver,
and am trying to test both proper and improper USB device removal.

Thanks !
