Hello Greg. I just compiled in the cdc-acm to check and no, it doesn't work.
That's all I get from the log:
usbcore: registered new interface driver cdc_acm
cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters
No more, no char devices are generated.

I don't get any char device; I have a customized kernel config (3.7.6) so maybe
there's something wrong with it? Other USB serial devices (like for
instance those based on Winchiphead CH341) are working without problems
(with the appropriate driver).

Attached.
