Usb bluetooth adapter: i need some specific model?

[santysos]

Hi, i'm going to buy an wiimote and nunchuck for playing games with dolphin, but, i have a question that i couldn't find the answer yet...

I will buy an usb bluetooth adapter, but, there are many models to choose, i need something specific to connect the wiimote to it ?

I need a bluetooth 2.0 "EDR class 2" adapter?
it have to be compatible with ad2p?
it got to have some specific range? (i've found an broadcom mini adapter with only 10m of range)

Thanks a lot!
