I am getting the exact same issue. The Wiimote lists as a "Bluetooth HID Joystick" under Device Manager, but it's got the yield sign over it indicating there's a problem with the drivers. And of course any any Wiimote-related app I start states that it cannot find the Wiimote in the HID Device List.
My BL Bluetooth software can find the Wiimote and connect to it just fine, tho I am apparently having problems getting it "paired". Every time I try to pair it up, I get an authorization failure.. despite using no password on the pairing. Can anyone offer any suggestions?
