The Umss.exe sample shows how two drivers can be used in
tandem to support a universal serial bus (USB) mass storage device on a
Microsoft Windows 98-based computer. The sample consists of source code for a
Windows Driver Model (WDM) driver and an IOS driver, which work together to
support a USB mass storage device. The Umss.exe file also contains a sample
.inf file that shows how to install the two drivers.

| • | How to support a USB mass-storage device on a Windows
98-based computer that is compliant with the Control-Bulk-Interrupt Transport
defined by the USB Mass Storage Device Class. |
| • | How to create a virtual child object in a WDM driver, and
use it to load a separate driver. |
| • | How to communicate between a VxD and a WDM
