I am working on USB hub application and referring to 'CYPD3125 Notebook solution with Dual Role functionality' example. I am looking at more detailed description for the events of app_evt_t than what is mentioned in section 6.24.4.2 in "EZ-PDTMCCGx Firmware StackAPI Reference GuideVersion 3.3.0"

Also wanted to know the order of this events.

Thanks in advance.
