CDC-ACM Module

[cyanarnofsky]

Is this built into the kernel of Raspbian? I am trying to get a EVDO modem working and I am told it should report as /dv/ttyACM0 but right now when connected it shows up as USB ports 0-3 rather than getting assigned to ACM0.

Thanks!~

[AndrewS]

Maybe you just need to try using /dev/ttyUSB0 instead of /dev/ttyACM0 ?

[jtcave]

Yes, Raspbian has CDC ACM drivers built in. They're plug-and-play, so /dev/ttyACM0 should show up when you plug your adapter in if it really is CDC ACM.

At least, it did for my 56k modem. I've never used a mobile broadband adapter, and I don't know if they usually demand special snowflake drivers or not.
