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). > From what I read, there are three mode for the Palm Pre USB.

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. > >> You may want to check that out.

We know that it was rndis, because it uses rndis function driver in Linux device code. > By the way, I do not know anything about the Linux Gadget driver.

We try to will provide more detailed information.
