I am trying to install a bluetooth dongle on my system. When I try to do the same I am getting a error. The error is Opening the modem device failed with error 000005aa. It looks like some kind of hardware conflict in my system. I can see the modem listed but somehow it is not working really well. I am trying to install the same directly through device manager. But there can be some other thing also responsible for the same error. Can anyone guide me on it.
