+=== Product Description names ===
+This example shows that if you have set the Product Description for easier identification of a NinoTNC, it can also be used to create the name links in ''/dev''
+<file shell /etc/udev/rules.d/99-ninotnc.rules>
+SUBSYSTEM=="tty", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="00dd", ATTRS{product}=="NinoTNC-GB7BMY-VHF-2m", SYMLINK+="NinoTNC-VHF-2M"
+SUBSYSTEM=="tty", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="00dd", ATTRS{product}=="NinoTNC-GB7BMY-HF", SYMLINK+="NinoTNC-HF-40M"

+<code>jonathan@GB7BMY /dev> ls -lah NinoTNC-*
+lrwxrwxrwx 1 root root 7 Aug 20 13:23 NinoTNC-VHF-2M -> ttyACM0
+lrwxrwxrwx 1 root root 7 Aug 20 13:23 NinoTNC-HF-40M -> ttyACM1</code>
+This format could also be used in place of the two lines above, and would create the devices in ''/dev'' named with the exact product description.  It is not recommended to have spaces in the product description if you use this method.

 ==== Final Steps ====
 To activate the newly-created rules you can either remove and reconnect the NinoTNC USB cable, or use the command ''sudo udevadm trigger''.  Once either has been carried out, the new devices will be visible in ''/dev'' for use in your application.
