As a workaround, I'm using the faulty unit to pair devices and am using a cheap USB Wii Sensor bar right on top of the Dolphinbar which works fine.

While it is nowhere near as good as real wii bar (pointer is very jumpy), it does work well when it is placed on the bottom of a display.

This is the best and only sensor bar you should be buying to play on Dolphin

Only complaint is that the cord is a little bit short, the bar doesn't seem to like USB extension cords, and it took me a while to figure out how to get it to install the drivers (wouldn't go into driver install mode for whatever reason), but I'd only take half a start for all that.

The bar worked great for two days, and then I woke up one morning to the sensor bar would not show the wiimote cursor on the screen, the buttons would work, but the screen would keep telling me to point my wiimote at the screen which I was doing

The four modes work as per the directions.
