I think this is the problem: AFAIK, the kind of modem that is supported
by cdc-acm should have Class 02, Subclass 02, Protocol between 01 and
06. This Apple device does not seem to identify itself as USB_CDC_SUBCLASS_ACM.
(I do not know what Subclass 03 is.)

Did you send the above output to Greg KH? Did he comment on the Sub=03
issue?

Does this modem maybe have different modes of operation, can it be
configured by a switch or by an Apple-specific configuration program to
be ACM compatible?
