NetDCU-USBLoader and Windows 7 64 bit

    I have the following problem on a Windows 7 Professional German 64 bit system.


    I have installed NetDCU-USB-LoaderSetup_x64_v22.exe dated 2011-08-10. There was no Version 1 installed.


    Powering on the starter kit I see in the Device Manager under USB Controller a new entry labeled "Unknown Device". Even when using the DU command in the boot loader over DCUTerm there will be no connection from the NetDCU-USBBootloader.


    The target board is a NetDCU 11 board.


    Code
    1. Microsoft Windows CE Ethernet Bootloader Common Library Version 1.1 Built Jan 27 2009 12:16:07
    2. Microsoft Windows CE Bootloader for NETDCU11 Built Feb 6 2009
    3. Portions copyright (c) 2007 F&S Elektronik Systeme GmbH
    4. Boot Loader, Version 1.35
    5. StepStone Loader, Version N911


    Is this a known problem?
    Uninstall and reinstall does not help.
    I'm a local adminstrator on the machine.
    During install both checkboxes for NetDCU-USBLoader and FSUSBBoard driver are active. There are no error messages during install.

    I installed the NetDCU-USBLoader on a Win 7 32 bit system and it is working.


    Next I tried again on my Win 7 64 bit system and I got it to work.


    It is absolutly neccessary to do the work in the following steps:
    1. Boot the NetDCU with a running DCUTerm and pressed Shift+s
    2. Type DU into the DCUTerm program
    3. Connect the USB cable
    4. Start NetDCU-USBLoader


    When the USB cable is connected during boot of the NetDCU a wrong driver will be loaded.
    In this case unconnect the USB cable, wait a short time and connect it again after the DU command. This will also load the F&S Borad driver.
