+
+    libusbgx: Add interface name for Feature Descriptors
+
+    This adds interface name required for "Feature Descriptors". If
+    specified, we can assume that a Feature Descriptor with the
+    interface name of the specified string is understood by the
+    kernel (e.g. interface.rndis).
+]
+
+it only added Feature Descriptors for RNDIS, NCM also needs that, or
+else it could not be recognized by Windows systems.
+
+Add Feature Descriptors interface name for NCM.
