Right, it is probably impossible to catch all strange cases, but the way how the Linux implementation of sanei_scsi_open_extended tries to check, if an SG file is opened, can most likely also be implemented for other OS and also not only for SG device files: Simply try an ioctl which is specific for the device type, SG_GET_TIMEOUT in the case of the Linux SG driver.
