The try_src_count and try_snk_count may still be 1 after enter into unattached state. This may be caused by below case: - SNK_TRY->SNK_TRY_WAIT->SRC_TRYWAIT->SNK_UNATTACHED - SRC_TRY->SRC_TRY_WAIT->SNK_TRYWAIT->SNK_UNATTACHED The port->attached is not true at the end and tcpm_reset_port() will not be called. This will reset counter into for these cases, otherwise the tcpm won't try role when new cable attached.
