3 * Driver for SanDisk SDDR-09 SmartMedia reader
10 * The SanDisk SDDR-09 SmartMedia reader uses the Shuttle EUSB-01 chip.
11 * This chip is a programmable USB controller. In the SDDR-09, it has
12 * been programmed to obey a certain limited set of SCSI commands.
13 * This driver translates the "real" SCSI commands to the SDDR-09 SCSI
