I found my problem. I use ExpertGps for all my maps and interface between my garmin and the computer and when I installed it, I did not finish the whole process of identifying my gps and telling the computer what type of port to use. After I set the port to usb to serial it fixed the problem. But to answer your question, yes I downloaded my drivers from mygarmin. Thanks for your input and have a great day.
I am try to get a program working that you can use a gps with it and down load and up load wave points. The gps that I am using is a garmin etrex vista and it has a serial connector. I am using a RS232 to usb adapter that is advertise to work with windows 8 32bit and 64bit. I have down loaded the drivers for my gps from gamins web site. When I connect my gps to the usb port the computer recognized that is was connected and configured the usb port for it. When I try to upload or download to or from the gps I get a popup window tell me com port 4 was unable to open. When I look at the devise manager and select usb to serial port it says it is com port 7. I have tried everything I know to do to correct this and just keep getting same results. Any ideas or know what the fix is. Thanks Phil
