This driver enables numerous USB-based storage devices on Windows CE OSs, such as hard disks, floppy disks, CD-ROM drives, ATA Flash Readers, and so on. The goal is to write the USB storage class driver as a block device driver that plugs into an appropriate file system driver at the upper edge so that applications can use it seamlessly.
