+	  This driver provides support for CDC MBIM (Mobile Broadband
+	  Interface Model) devices. The CDC MBIM specification is
+	  available from <http://www.usb.org/>.
+
+	  MBIM devices require configuration using the management
+	  protocol defined by the MBIM specification.  This driver
+	  provides unfiltered access to the MBIM control channel
+	  through the associated /dev/cdc-wdmx character device.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called cdc_mbim.
