 the driver what you have, using the type module parameter. There is no
 way to autodetect the devices. Support for different pinout configurations
 can be easily added when needed.

 	  This driver is a replacement for (and was inspired by) an older
 	  driver named i2c-philips-par.  The new driver supports more devices,
 	  and makes it easier to add support for new devices.
-	  
+
+	  An adapter type parameter is now mandatory.  Please read the file
+	  Documentation/i2c/busses/i2c-parport for details.
+
 	  Another driver exists, named i2c-parport-light, which doesn't depend
 	  on the parport driver.  This is meant for embedded systems. Don't say
 	  Y here if you intend to say Y or M there.

  * RNDIS is NDIS remoted over USB.  It's a MSFT variant of CDC ACM ... of

  * for Ethernet links is "CDC Ethernet", which is significantly simpler.
+ *
+ * NOTE that Microsoft's "RNDIS 1.0" specification is incomplete.  Issues
+ * include:
+ *    - Power management in particular relies on information that's scattered
+ *	through other documentation, and which is incomplete or incorrect even

+ *    - There are various undocumented protocol requirements, such as the
+ *	need to send unused garbage in control-OUT messages.
+ *    - In some cases, MS-Windows will emit undocumented requests; this
+ *	matters more to peripheral implementations than host ones.
+ *
+ * For these reasons and others, ** USE OF RNDIS IS STRONGLY DISCOURAGED ** in
