Yes, this is not going to be easy. AFAICS, both the device id and also the class codes(?) are used by other devices which really are wwan devices.

So unless I've missed something here, I don't think we can make the driver fix this. Userspace will just have to deal with it somehow. I guess the last resort will be asking the user? Unless it's possible to do a dhcp probe? This might be useful for other "hostless" modems as well.

I don't think it's possible to ever get the wwan device type 100% correct. There is a certain amount of guessing in there.
