We will need the values of "ID_VENDOR_ID" and "ID_MODEL_ID".

Then we use udev to automatically send the activation command. This way, the device will get activated automatically when it gets plugged in.
<sxh bash; gutter: false>
install -vbD --owner=root --group=root --mode=0644 -T <(cat << 'EOF'
# Initialise Apple SuperDrive
ACTION=="add", ATTRS{idProduct}=="1500", ATTRS{idVendor}=="05ac", DRIVERS=="usb", RUN+="/usr/bin/sg_raw /dev/$kernel EA 00 00 00 00 00 01"
EOF
) /etc/udev/rules.d/96-applesuperdrive.rules
</sxh>


If you don't want to use udev, this is how to do it manually:
<sxh bash; gutter: false>
# find the device
ls /dev/sr*
# send the magic string to activate the device
sg_raw /dev/sr1 EA 00 00 00 00 00 01
# to eject the media from command line
eject /dev/sr1
</sxh>
