I have been trying to sync my wii fender strat guitar and keytar up to the wii for some rockbanding but they will not sync. They both just flash lights and do nothing else. I have the official rock band 2 dongle (with the two usb ports) a drum dongle (with just a sync button) and a psycosis (?) dongle with a sync button that blinks red.

Am I missing a dongle or some such?
