There was no CC ;) CC is enough of course.

No, don't! The user shouldn't care what protocols are used. I just wanted to
notify you that using rfcomm won't work here.

This is exactly what should happen, yes. No PIN as BlueZ generates it for you.

Did the device show up in /sys/bus/hid/devices ? Did you check dmesg? I think
you got the device connected successfully, it just doesn't do anything useful
without configuration ;)

You may also want to have a look at
https://wiki.archlinux.org/index.php/XWiimote
This is a short summary of the current state of the xwiimote drivers.
The user-space
part is still under development so you might want to look at cwiid instead.
