+
+USB Template
+------------
+
+USB Template driver is initialized based on the value of `hw.usb.template` 
+sysctl variable. To set the variable use the `sysctlbyname` system call 
+as follows in your application,
+
+  .. code-block:: c
+		
+		int template = 1;
+		sysctlbyname("hw.usb.template", NULL, NULL, &template, sizeof(template));
+
+You can set the variable at runtime using the shell with the syctl utility.
+
+  .. code-block:: shell
+		
+		sysctl hw.usb.template=1
+		
+NOTE: Template 1 is the CDC Ethernet.
