Starterware/TPS40400EVM-351: Digital Fusion Power tool cannot detect TPS40400-EVM-351 board

Part Number: TPS40400EVM-351
Other Parts Discussed in Thread: USB-TO-GPIO, , TPS40400

Tool/software: Starterware

hi,

I am following the TPS40400EVM-351 user guide by connecting the USB-TO-GPIO cable to TPS40400EVM-351 board. Power up the board with +5V as mentioned in the user guide.

However, when I power up the Fusion Digital Power Design tool, it cannot detect the board. I am very sure the pin direction is correct and the UPB to GPIO driver is detected correctly in Device manager (Win 7, 64 bits). Even I set to slower speed of 100KHz, the result still the same as below.

Any advice, how can I bring up the Fusion Digital Power Design to detect the board with error message " No Devices Found"?

Best regards,
