@c_th1 Yes, this disables all data transfer capabilities in the USB controller. Unless you're worried about forensics companies somehow exploiting the firmware of the USB controller itself, which is unlikely, but not impossible, considering that some companies seem to specifically hire people with knowledge and understanding of the USB protocol/hardware, as well as GrapheneOS.

If you're really worried about these kinds of things, you can disable USB completely and use wireless charging to charge your device. Or you can at least disable USB completely when you're at an airport, or crossing a border.
