I just did one more experiment. I've selected to install the driver manually in 
Windows wizard and I seleted the standard linux.inf for Linux RNDIS Ethernet gadget
(from Documentation/usb/linux.inf, we used it earlier for the standard g_ether usb
gadget module in RNDIS mode, it is available for example here: 
http://beagleboard.googlecode.com/files/linux.inf ). 

I was really surprised, the driver installed correctly and RNDIS connection started 
working! So the real problem is to create a proper .inf for Windows (that linux.inf
was not recognised automatically).

Modes of operation of the Palm Pre gadget drivers are selected by changing a product
id. We added another case (0x0102) in that switch, where we registered only rndis
and mass storage functions. We loaded that gadget driver with our (0x0102) product id.

We know that it was rndis, because it uses rndis function driver in Linux device code.

Ok. We try to will provide more detailed information.
