BQ40Z80EVM-020: No Acknowledge from device

Hi, 

I'm having issues with connecting my EVM to BQstudio. When I open the Battery Management Studio the "target selection wizard" pulls up as shown below with the auto detect of my device. I then find the BQ40z80  as shown. When I open that I get a series of error messages saying, "No acknowledge from device." I'm suspicious that the "_04" of the auto detect is the issue. If so, is that just a firmware change?

Thanks, Daniel
