I keep trying the latest versions of Parallels hoping that this will be solved to no avail. I can not get windows XP to connect to my Delorme earthmate GPS with USB on my Macbook. I have the GPS and an engine monitoring program I use in my motor home. The GPS uses GPS and the engine program uses serial, which I have an adapter for. I can get them both to work in Boot camp but not Parallels which would be my preference. Dale
