Have to admit I've never tried it on a 770; I know the USB stuff is a lot more difficult because to get host mode working don't you have to feed power back into the tablet or something odd like that?

Anyways, you said that the lights come on on the device so that's usually a good sign, and if the dummy IAP actually automatically appears that's also a good thing as it means the UDEV stuff is running. Is the 2008HE inline with Chinook or Diablo by the way? Because I know they changed the ICD (the thing that manages internet connections) in Diablo, and thus why there are still two version of the package though I believe that I tried to make the Diablo one as backwards compatible as possible...

One thing I can recommend trying to help troubleshoot is going into xterm, becoming root, and 1) type in "route" and see what the routing table shows (i.e. does it see your eth0 adapter with an IP), 2) do an ifconfig (and see if eth0 is listed and if it does indeed have an IP and 3) if both those are good try a ping to see if traffic will actually go across the interface. If the ping works then it's definitely something goofy with the ICD stuff...

Thanks!
