I am trying to use a leanardo with a dell precision 64 bit win 7, and i spend 90% of my quite limited spare time just trying to set up stable communication, COM ports seem to come and go almost randomly or be "in use" even if disconnected. Have tried various help sections on the web, but still canot get a stable reciepy for geting going with a basic connection. occassionally fluke it but next time i can spend 3-4 hours trying to get started.
Does any one else have these problems and a solution.
