Two bugs on the SCA: - With no images found, the RAW fallback resolved the strapped SCA ID into fallback_id for initDevice() but then opened the raw disk on the hard-coded RAW_FALLBACK_SCSI_ID, so the drive appeared on the wrong ID with another ID's settings. Open on the resolved fallback_id. - check_is_sca_model() latched is_sca_proto as soon as the write to the prototype I2C address succeeded, even when the following read failed and the probe returned false. Later flag reads would then address the prototype chip on a board that never answered as one. Latch only after the chip actually responds.
