To the best of my knowledge it's a user space driver for rndis, I don't
know what it's status is however.

I think I know what we need to do. We should actually be attaching to
the outermost leaf node, if that's the right way to say it. For
instance, for my WM2003 device
/org/freedesktop/Hal/devices/usb_device_502_16e3_noserial
has a child
/org/freedesktop/Hal/devices/usb_device_502_16e3_noserial_if0
has a child
/org/freedesktop/Hal/devices/usb_device_502_16e3_noserial_if0_serial_usb_0
The final one is the device that dccm attaches to, but the second is the
one that has info.linux.driver=ipaq. So in your case I would really want
to attach dccm to the child. So the rule should contain
<match key="@info.parent:freebsd.driver" contains="ucom">
Then we'd need to get the unit number from the parent, that can be done
with the hal tools.
Is that the complete listing of both those devices, and is the child the
outermost leaf ie. it has no children ?
