The fusbtc driver provides support for the Fairchild FUSB302 USB Type-C port controller. It takes care of plug and unplug events on the USB Type-C port and discovers the orientation of the plug so that the USB SuperSpeed pins can be routed correctly. Additionally it enables power on the USB Type-C port when a sink is connected to power attached devices.


The fusbtc driver first appeared in OpenBSD 6.6.

The fusbtc driver was written by Patrick Wildt <>.
