I have tried the above comment and It doesn't work. How about to change the judgement like as below - if (tcpm_port_is_disconnected(port)) + if (tcpm_port_is_disconnected(port) || !port->vbus_present) The hard_reset_count not reset issue is following by the below order 1. VBUS off ( at the same time, cc is still detected as attached) port->attached become false and cc is not open 2. After that, cc detached. due to port->attached is false, tcpm_detach() directly return. And that's why hard_reset_count is not reset to 0. > > Guenter
