Hi,
You might want to check out:

I havn't tried it, and Im not sure if it is a CDC driver... but
it might be a good starting point....
Another idea is to start with the start() (in the apple cdc
ethernet driver) method, and have it call super::start(), then
IOLog("hello world") (to send a message to the system log), and then
immediately return. That, at least, should not panic, and you shoud be
able to see the message by opening up the Console application and looking
at system.log. If you are patient, you might be able to narrow down where
the panic is occuring.
