I've been having trouble connecting my new Oregon 650 to my PC via serial connection (USB), it is hit or miss on when the GPS recognizes the serial connection and goes into USB mode. Most time the GPS starts up and then shuts itself down with no connection. Everything else on the GPS is working fine. Is this a known issue? Running Basecamp on Windows 7.
