I'm getting mad! Now bluetooth on PC works again, keyboard is fully functional with every single key and every symbol .... but now it doesn't connect to N900 any more. Again error message "host is down". That was the point I have already been at before installing bt-hid-scripts. You are sure I don't need any of these packages?
I think I'm gonna give it a break now and try again later. I'm really getting angry now. (Not at you of course, I really appreciate your help, but when one part is fixed another one gets loose again, that's frustrating )
