11 / 35 page  www.ti.com Software Start up When the software has been installed and the USB cable has been connected to the TSW140x EVM and the PC, the TSW140x USB serial converter should be located in the Hardware Device Manager under the Universal Serial Bus controllers as shown in Figure 6. This is a quad device which is why there is an A, B, C, and D USB Serial Converter shown. When the USB cable is removed, these four will no longer be visible in the Device Manager. If the drivers are present in the Device Manager window and the software still does not connect, cycle power to the board and repeat the steps above. If the GUI starts up but freezes before it brings up the "Connected to Board" dialog, or takes an unusually long time for other actions to occur, it is possible the USB being used from the host PC is operating at USB 1.0 speeds. A common indication of this is when the status bar on the bottom left of the screen keeps reading "Disable all Controls" upon loading the software without ever going to the "Connect Board Dialog". The GUI is designed to run at USB 2.0 speeds and some computers have USB 1.0 ports on the front panel and 2.0 on the back panel. Using the ports on the back of the PC if at all possible is recommended. The .exe file installs the FTDI drivers during software installation. If after connecting the USB cable and Windows lists the board as an "unknown device", this could be caused by corrupted FTDI drivers being installed on the computer. This happens in cases where the same computer has been used to interface with previous products that used FTDI drivers. In this case, users are advised to download and install a utility from FTDI at http://www.ftdichip.com/Support/Utilities/CDMUninstaller_v1.4.zip. The help file for using this utility is found at: http:/www.ftdichip.com/Support/Utilities/CDM_Uninst_GUI_Readme.html Users will need to use the following hex values to uninstall previous versions of the ftdi drivers: Vendor ID (VID): 0403 Product ID (PID): 6010 After removing the drivers for this PID and VID, re-connect the TSW140x USB cable and check if the TSW140x ports get listed properly in Device Manager.
