So I just got a Curve 8330 this week. It won't stay connected to the computer. I have already tried re-installing the desktop manager software and it still doesn't work.
What happens is that I'll plug in the phone, into a port in the back of the computer, and looks like it's connected on the phone for about four seconds but there's no sign of it connecting on the computer. It was working yesterday perfectly fine, so I have no idea what could have triggered this.
