When VBUS is not discovered within PD_T_PS_SOURCE_ON although Rp is detected on CC, TCPM switches the port to SNK_UNATTACHED state. SNK_UNATTACHED, however does not force TYPEC_CC_OPEN which makes the partner(source) to think that it is connected. To overcome this issue, force the port into PORT_RESET state to make sure the CC lines are open.
