In order to run the USB Example you must install the following software peices:

Software Link
USB Example Code
EVM5509A USB example source code, download and unzip to directory
Open Source USB library designed for use with Windows, download and install

For First Time Users
Install the LibUsb-Win32 ( libusb-win32-filter-bin- ) drivers to the
   c:\Program Files\LibUsb-Win32-
Unzip the EMV5509A USB example code ( ) to ( TI install directory )
Copy file: evm5509a_libusb.inf

to the LibUsb-Win32\bin directory
   c:\Program Files\LibUsb-Win32-\bin

evm5509a_libusb.inf contains information used to identify the EVM5509A's PID/VID IDs used in the usb examples

Follow these steps to run the USB Exmaple:

  1. Load Project
    Open the usb.pjt Code Composer project using Project -> Open and selecting usb.pjt. It is in the directory

  2. Load Program

  5. For First Time Users
    Windows has no information about the EVM5509A prior to plugging in the usb cable, once connected the EVM5509A will send its PID/VID to Windows.
    The PID/VID information matches the evm5509a_usblib.inf file above, and is what Windows uses to determine what type of usb device is connected. When the drivers window appears, point to the (LibUsb-Win32 install directory)\bin.
