Our customers are sometimes having a problem when installing the drivers on new Windows 7 systems. The drivers appear to install correctly, and the COM port shows up under device manager, but when our software runs it cannot find the COM port. When we present a list of COM ports to the user (by enumerating the list from Windows Registry) the port does not show up.
We are using driver version 6.5.9018.1 for Windows 7 installations.
Sometimes the ports work just fine in Windows 7, and sometimes they do not. I am not sure if the problem only happens on 64 bit versions of Windows 7, but it is possible.
Our customers running Windows 8 are installing version 6.7.1.0 and are not reporting this issue, so it appears to be either a Windows 7 problem, or a problem related to version 6.5.9018.1, or both together.
Does anyone know of this issue? Is there a solution?
Thanks for any and all help.
