Guess that means the interface is not CDC ACM compliant?! *bummer*
I don't have any other information than an USB flow control log. The
communication scheme is: Send/Receive AT-Command/Feedback over the
Control-Pipe and Notifications (3 Bytes: type, length, unknown) over
in/out interrupt pipes.
Any idea if this equals any standard USB Control Model at all?

Hi,
I tried to match interface #0 with a codeless kext with the
properties below but it fails due to: ISDN Interface: family
specific matching fails.
What's wrong? Do I also need to match the device itself?
It's not clear to me whether someone else responded to you as I'm
having email issue. forcing the device to match as a CDC device is
not going to solve the problem since interface 0 is marked as
vendor specific. Instead, you want to force Interface 0 to match
as a CDC supported interface.
In doing this, there is the assumption that the interface matches
the CDC specification. If you look at the mailing list for USB and
perform a search on "codeless", you will find several samples
referenced.
best wishes.

Hello,
I'm working on a software to access and configure an ISDN phone
connected via USB. Currently the software accesses the device
from user-space with the composite USB driver that's provided by
OS X by default (see USB-Probe and IOReg output below), with its
own (and somewhat incomplete) AT-Command-Set.
The phone supports the complete AT-Commands-Set (and additional
vendor specific commands). So far everything works fine but now I
stuck...
I want to make the phone available as modem, as this would make
communication with the phone much easier - and it could be used
as modem too. I've tried to modify the USBCDC drivers (10.3.9) to
match the device but failed (this is my first USB/driver project!).
1. Is there a way to force OS X to match the device with the
systems default CDC-Driver instead of the composite one?
2. Or do I need to write my own kernel extension? If so, is there
a 10.4.x version of the AppleUSBCDC driver source?
3. The device has 4 interfaces (at least #0 and #1 can be used
for AT-Commands), can I attach more than one interface, e.g. one
as CDC and the other as composite?
