Any diagnostics messages from cdce in /var/log/messages?

From the cdce(4) manual page:

    The cdce driver does not support different media types or options.

Try without the CDCE_FLAG_NO_UNION flag in cdce_host_devs[]?

Have a look at the source code for the Linux driver. Maybe there is some
initialization or flags necessary that the cdce driver isn't doing.

Unpacking the windoze drivers and looking through the files (e.g. .inf files)
sometimes yields interesting info.

But looking for a replacement for which a FreeBSD driver exists might be a
good idea. :-(
