I don't understand your question ... SCSI_IOCTL_SEND_COMMAND sends a
SCSI command to the device.  Your example of test unit ready above does
just that ... it sends a Test Unit Ready command to the device using
SG_IO ... exactly what do you not understand about using SG_IO to send
commands to the device?
