Having said that, it appears your problem is that the BCN44 is not recognized by BC manager which could mean that it will not work with it or you haven't installed the correct drivers for your OS.
A quick search shows that Mountain Utilities has a specific editor for BCN44,

It would appear this is your first problem. You need BCN44 Manager NOT BC manager.
One you have this installed you need to install the appropriate driver for your OS then it should recognise the BCN44.
