There is some better CDC parsing code available, which could be grafted onto 
the ACM driver. See the old cdc-ether driver.

This would be trivial to fix - you can read it from the CDC descriptor.

The reason for this is that people expect to use AT commands, which IIRC is 
the protocol 1.

Presumably you can do at least the OBEX stuff in userspace. I think that there 
is an project working on this (OpenOBEX?).

Also, it would be worth looking at the bluetooth stuff, which is targetted at 
a very similar problem space, and uses at least some of the same buzzwords.

Do you actually have hardware that implements the standard? Can you say what 
it is?
