So far, this seems to be correct. Right; though at some point here we do want to start enabling the pseudo ethernet interfaces on these devices too. PPP has too much overhead for higher speed networks (ie, HSDPA 7.2+) plus it's more complicated and error-prone than the pseudo-ethernet method. So I hope we eventually reach a world where we're not using PPP at all anymore. But the usb_modeswitch command shouldn't be an issue until we actually have a roughly working driver for these devices anyway, then we can figure out what to do about switching.
