Doesn't make any difference either.
Compiled cdc_acm in the kernel, not as a module. Doesn't make any
difference, except for that it says 'a reboot is necessairy' en then it
freezes. Still no symbols.

Google didn't tell me anything useful, nor did you.
This took me days already.
I told you all you need: plug in a modem that needs cdc_acm.

Wim.
