Hi, I am a windows newbie, so thank you very much for your patience and kindness Xiaofan . Unfortunately, I don't understand things in the second :-) .
I deinstalled the amontec drivers from the device manager menu and even the devices . I've also deleted the ftd2XX.sys file from the WINDOWS tree . I plugged the programmer off, and a little later plugged it on . I selected the manual selection , but at the bottom of the first window that appears after having chosen to do a manual installation , appears a yellow exclamation mark signal stating : " This driver has not been digitally signed " even before that I tell the path to the driver I'd like to install . Seems windows is hooked up to the amontec jtag driver that I installed first and that even before deinstallation of it, it is still there somewhere on the computer . In this dialog if I click on Next, the installer tries to install the amontec drivers without asking for it , but I guess it as it asks for the ftd2XX file that I deleted, and otherwise if I click on Provided Disk , I can tell the directory that contains the .inf file previously created , but finally the installer answers that the directory specified doesn't contain any information relevant for the device . What should I do ?

As I mentioned before, >> It clearly says that "this version was compiled to use libftdi + >> libusb-win32 libraries". But you just do not believe me... You can not use the Amontec drivers (ftd2xx) with the binary which is using libftdi. You need to install the libusb-win32 driver. Freddie provided the inf file to do that. It is inside the Zip file. libusb-win32_ft2232_driver-100223 ********** info.txt ***************** WHY LIBUSB-WIN32 DRIVERS? _________________________ Since June/July of 2009 due to alleged GPL license violation OpenOCD cannot be distributed with support for ftd2xx.dll library. That's why FT2232 JTAGs have to be used via libusb-win32 drivers, and OpenOCD will be linked with libftdi library. Because of that OpenOCD users have to use different JTAG drivers. This small document provides a basic "how to" of libusb-win32 drivers for FT2232 based JTAGs. Users who need OpenOCD linked with ftd2xx.dll can build the software from sources. DEVICES SUPPORTED BY THIS DRIVER PACKAGE ________________________________________ The .inf file provided with the driver in that package has entries for most of existing FT2232 JTAGs. These devices are: - Amontec JTAGkey ... DRIVER INSTALLATION ___________________ If there were FTDI drivers installed in the system, they have to be manually removed (via system's Device Manager) and then libusb-win32 drivers have to be installed manually. In case of "JTAG + UART/RS-232" devices only the driver for the JTAG channel needs to be removed. In case of "JTAG-only" devices the driver for the second (unused) channel also can (but doesn't have to) be replaced. Uninstallation of ftd2xx.dll driver: When the device is plugged, open the Device Manager (Control Panel > System > Hardware > Device Manager), right click on the JTAG device (in "Universal Serial Bus controllers" group) and Uninstall it. Now unplug the JTAG and wait a few moments. Installation of libusb-win32 driver: Plug the device to the USB port of your PC. The system should discover a new device and the installation wizard should be started. Don't use automatic methods (as this will probably install the drivers you just removed) - use "Don't search. I will choose the driver to install" (fully manual mode) instead. Succesfully installed driver(s) will be displayed in the "LibUSB-Win32 Devices" group in the Device Manager. ... *************************************** -- Xiaofan http://mcuee.blogspot.com
