- attach your device to an USB-port

And there you have a perfectly working USB Mass Storage Driver for your Windows-system.
The Ntmap.sys and Ntmaphlp.pdr files are needed for the driver to work and they are included here just in case you won't be able find them from anywhere else (installation CD or your hard disk). Originally this driver is from Win2000 installation CD.
