It should be correct.
And can you check your schematics and verify VBUS is supplied by
pm8150b_vbus and not say by an external IC ?
I haven't schematics, so I can only use hacking code to test it.

Could you show the state of TYPEC_MISC_STATUS_REG @ 0x0b ?

I wonder if BIT(5) TYPEC_VBUS_DETECT is set ?

BTW what sort of device have you connected here and is it self-powered ?
