I'm getting a similar problem. I could connect my BT21 to a pc using windows xp with the widcomm drivers. I can also get it working with the mini bluetooth usb.I'm now trying to get it working on windows 7 x64 and I have the problem that when I try and use the default windows drivers the lights never stop flashing and I cant get any program to use the remote (wiinremote, smoothboard .ect). If I uninstall it and then use smoothboard to connect it the lights stop flashing and only one light remains illuminated but smoothboard says, wiimote error, "Error reading data from Wiimote...is it connected?" It shows up in the bluetooth devices and devices and printers as "Nintendo RVL-CNT-01"I've tried a combination of things, going into devices, removing HID devices, removing bluetooth .ect, can't seem to get it going!
Update: If I uninstall with device manager in the control panel, reset and then pair with smoothboard 2 from the outset (multiple wiimotes enabled) it gets 1 wiimote found, 0 connected. It then tries to connect it and i sometimes get a message saying the device was not installed correctly. Sometimes it says it did install correctly, and the lights continue to flash and 1 found 1 connected appears, before it goes back to "learning" and smoothboard continues to try and pair indefinitely in the same cycle.Pairing with Win 7 still always "works" (except lights don't stop flashing), if I try and connect with smoothboard after this then I get the same connecting loop over and over.I have tried with the BT21 and the Mini Usb Bluetooth adapter sold on the sites here.
