Hi Have just started running Parallel desktop with Vista to enable me to access a website and a few programs that I cant run on a Mac. I can access the program (Tasknav for glider flight planning and analysis) but cannot seem to connect the device - it is connected with a usb/serial adaptor. I am also trying to connect to a Garmin GPS with a similar adaptor but although the Garmin test page reckons the correct driver is installed I cannot detect the device to update it. Other devices seem to work with a usb connection. Anyone offer any advice? Thanks Paul.
