Unpairing from the Wii still doesn’t work. Which means, even an unused Wiimote can’t connect. Is this a permission problem, perhaps? Maybe a script is being blocked due to insufficient permissions.

What do you (or anyone reading this) have in your /etc/profile file? What about the /etc/rc.local? /etc/udev/rules.d/wiimote.rules? /etc/cwiid? I’m wondering if I made a mistake in one of these files.
