Yep, using a bluetooth dongle. As far as I can tell it's as dead as a can of spam, no response from any of the buttons, no cursor movement, nothing. I was able to obtain the MAC address, so it must be communicating with the dongle on some level at least.
I don't have motion+ attached, or the nunchuk.
After the blue lights have finished flashing, does the first one remain on once connected, or are all of the blue lights meant to turn off?
Yes, the wiimote's MAC address is in /etc/wminputd.conf
I have just noticed that there is some troubleshooting information at the bottom of the wiimote wiki page that describes a problem similar to mine, I will give that a go first. I also have another bluetooth dongle that I might try failing that. Will keep you posted, thanks for your suggestions.
