Hello, After looking through the Cypress example projects distributed with the FX3 SDK, it seems that every BOS descriptor has values of 0 for U1 exit latency and U2 exit latency. I also don't see any specs for these in the FX3 datasheet (though maybe I missed it?) Why are these values set to 0 in the SuperSpeed BOS descriptor? (last 3 bytes). Are they really so close to zero that this is accurate? Is zero a special value? Thanks, Dan Ford

Hi,
There is no specific reason for setting it zero. The value in the descriptor file wont change the actual exit latency. You have to set it based on your application.
