Unfortunatly USB Type-C is handled in firmware on those computers. We can only query the status of some basic things using an interface called UCSI, but most details are completely hidden from the operatings system. There have been a lot of problems with the UCSI interface on older XPS 13 and Latitude systems. Some of those problems have a workaround in the driver, but not everything. Br, -- heikki
