I also have a mikomi dc-7120, and as I read at other forums, everyone has a problem. Most of it like not working correctly with vista, or when you downloaded the newest windows live messenger for vista, its stopped working. And the joy is, there is no correct driver for this one, because, there is no Mikomi company at all, its such a fake like Alba or Bush, many products of Argos. But, it is working with Skype correctly. Well, now I know, next time I'm not going to buy any nameless product.
