The kernel-mode still image driver for SCSI buses supports ReadFile by creating a command descriptor block (CDB) that includes a SCSI Read command. It supports WriteFile by creating a CDB that includes a SCSI Write command. User-mode minidrivers can specify customized CDBs by calling DeviceIoControl. 자세한 내용은 SCSI 스틸 이미지 I/O 컨트롤 코드를 참조하세요.
