Issue 117: Support for RNDIS

Reported by Nikolaus Schaller, Jul 22, 2010

The driver is currently CDC-Ethernet only.

It would be nice to integrate/port RNDIS from the Linux gadget 
drivers.

I'd like to get USB tethering working on Snow Leopard with an HTC 
EVO 4G.  It has been reported that Lion works with the 4G out of the 
box.
 
Is this output from USB Prober a RNDIS signature?

       Interface #1 - Vendor-specific   
            Alternate Setting   0
            Number of Endpoints   2
            Interface Class:   255   (Vendor-specific)
            Interface Subclass;   66   (Vendor-specific)
            Interface Protocol:   1

My mistake: I had USB Debugging turned on.  Interface Subclass 66 is 
Android ADB debugging.

Here's the output from USB Prober with USB Tethering enabled.

Sure looks like a RNDIS device to me.
