    Angry Connection Problem via USB "The port COM2 could not be opened: Port in use"

    Hi,
    since 4 months i have a problem. I cant test my apps from qtCreator via USB on my Nokia E7.
    E7 was new flashed. QtCreator is up-to-date.
    QtCreator recognise the phone if its pluged in.

    On the config window "symbian-devices" > "Run" > "Communication Channel" > "Serial: Serial port: Nokia E7-00 USB Serial Port (COM2)"

    On click at the testbutton in the corner i get a message with a red background: "The port COM2 could not be opened: Port in use"

    What can i do?!

    QtCreator: 2.4.1 (Qt 4.7.4 32bit)
    E7: Symbian Belle / 111.030.0609

    now... 2 days later, i format my pc and installed all things new.
    But now...
    "symbian-devices" > "Run" > "Communication Channel" > "Serial: Serial port: Nokia E7-00 USB Serial Port (COM3)"

    On click at the testbutton in the corner i get this message:
    ---------------------------
    Waiting for CODA
    ---------------------------
    Qt Creator is waiting for the CODA application to connect.<br>Please make sure the application is running on your mobile phone and the right IP address and/or port are configured in the project settings.
    ---------------------------
    Cancel
    ---------------------------

    Here the Screenshot, where everybody can see, that i choose "Serial" not "WLAN"...
    simply anyway what i choose...
    On my Phone "Coda (driver: Legacy (4.0) V 4.0.23)" is running!
