Why not issue 10 byte CDB first, then fall back to 6-byte if that fails (ILLEGAL COMMAND, etc.) instead of trying 6-byte CDB first, then falling back to 10-byte? Are there any devices which hang on 10-byte CDB's but work with 6-byte CDBs? Surely most devices are SCSI-1 and should at least recognize that a 10-byte CDB is illegal?
